Yes, you are correct. Your quadrant score should be at least 7000+ and average about 7500...:) Your antutu score should be about 17000...:) Otherwise, you may want to wipe both cache and reinstall the ET v1.4..

You are one of users that have issue with the ET..:( Are you running it now? Do you still have a problem of lag when you are updating apps from google store?

Last, Hund v3.4.2 has Dynamic FSync. It behaves a little diifferent than the manual FSync.. When you first turn on your screen, it will take about a minute for the FSync completely off. Yes, it is that slow and report it to Hund's post already...:) I don't think that we can do much about it because it has to finish what it is doing before turning off. Another side note, when the entropy available is at the maximum level, your device seems to run better and you have a better score even though your device is not using it..;) Weird is it?

I will update thhe first post with all these informstion when I have time..

Thanks for the reply...:good:
[Asus Transformer TF700] LetMeKnow:
Thanks for feedback..:good: You should feel that your wifi buffer is better with this version. You should play around with the congestion control to best fit your area. I will update that information for users to use later when I have time...:) I will list the tcp congestion available on Hund's kernel..:) Thanks Drenus for the information..:good:

[MENTION=5313285]LetMeKnow[/MENTION] Not sure if it's just me or my setup but 1.3 seems to run smoother for me than 1.4, particularly when browsing. Great work anyway though!
[Asus Transformer TF700] LetMeKnow:
Thanks...;) Your number are very good especially the second run on antutu. It is a very nice setup in order to obtain that score.:good: Do you do anything differences in setup? Thanks..
[Asus Transformer TF700] LetMeKnow:
Thanks for the feedback...:) Do you mean wifi buffering or slower internet? There are a few different things on Hund v3.4.2 comparing with 3.4.0..

1. Dynamic FSync

2. Using westwood congestion control instead of cubic...

3. Lower UV on both CPU/GPU to reduce heat which gives users more battery life.

All of those things may cause a different feeling...:) However, the testing data show that the v1.4 is faster but it may not be smoother..;)

If you like the v1.3, I would recommand you to use the new UV for CPU/GPU because it is better for your device over all. Please let me know if you need help in doing it...:) thanks..
[Asus Transformer TF700] yew123:
Yeah i meant slower internet as in when i scroll, there's more stutters compared to v1.3. But i agree it definitely does feel snappier. I'll run 1.4 for now anyway, thanks for the quick response and explanation :)
[Asus Transformer TF700] LetMeKnow:
I don't like the Dynamic Fsync that much....:( It is slow to turn off the Fsync and that is the part that I don't like.. However, my wifi is better with westwood contol...:good: You may want to change the congestion control to see if your wifi working better..

ATM, I may try to disable the Dynamic Fsync to see if it is working better....;) Moreover, I may apply the ET v1.4 on Hund v3.4.0 to compare with v3.4.2..:)
[Asus Transformer TF700] yew123:
Well i've flashed 1.3 again and i agree that the dynamic fsync isn't my favourite. It would be very interesting to see how 1.4 tweaks would run with hunds 3.4.0. If you end up doing that, i'd give it a try :)
[Asus Transformer TF700] LetMeKnow:
I will do that when I am back from a road trip...:) I will give an update how the new ET v1.4 on Hund v3.4.0;) I think that it is going to work better with manual Fsync off....:fingers-crossed:
[Asus Transformer TF700] LetMeKnow:
How is the battery life on the ET v1.4?

I am very aggressive on the UV on CPU/GPU on the v1.4...:laugh: You should see more battery if you are running v1.4.. Please report about the battery status if you are monitor your battery usage please....;) Thanks...
[Asus Transformer TF700] LetMeKnow:
New ET v1.5!

New ET v1.5 for Hund v3.4.0 and v3.4.2 will be here maybe tomorrow...:) The CFQ will be added on this v1.5.. The test data on the performance is very much the same as v1.4 with a deadline scheduler...:) However, it does seems a little more smoother. So it will be the default setting for this v1.5..;) The battery should be improved so please report back if you are keeping an eye on the battery status...:good:

The next project would be the universal kernel tweaks for all kernels so everyone can take a benefit from it...:)

Cheers and thanks everyone,

[Asus Transformer TF700] LetMeKnow:
Bench Test on ET v1.5!

After a few fine tuning on the cfq scheduler, the test result is improved a little bit comparing with v1.4 on the deadline scheduler....:) I believed that there is some room for improvements with a better understanding how the cfq function...;) I will continue to work on it to see if we can obtain some more performance out of it...

BTW, I am working on the zip file for the ET v1.5 and will upload them after work...:)
[Asus Transformer TF700] LetMeKnow:
The ET v1.5 release!

The ET v1.5 is working with both Hund v3.4.0 and v3.4.2. So users can choose whichever version that they prefer...;)

Hund v3.4.0:

--Manual Fsync disable

--TCP Congestion Control available: reno and cubic

--Governor available: interactive, touchdemand, conservative, ondemand, powersave, userspace, and performance

--I/O Scheduler available: cfq, deadline, row, and noop

--Governor optimization: interactive

--I/O Scheduler optimization: cfq, deadline, and row

Hund v3.4.2:

--Dynamic Fsync disable

--TCP Congestion Control available: westwood, reno, bic, cubic, highspeed, hybla, htcp, vegas veno, scalable, lp, yeah, and illinois

--Governor available: interactive, touchdemand, conservative, ondemand, powersave, userspace, and performance

--I/O Scheduler available: cfq, deadline, row, and noop

--Governor optimization: interactive

--I/O Scheduler optimization: cfq, deadline, and row

The default settings for the ET v1.5 on v3.4.0 and v3.4.2:

PowerSaving mode: CPU=1.4GHZ, GPU=520MHZ

Balance mode: CPU=1.6GHZ, GPU=600MHZ

Performance mode: CPU=1.8GHZ, GPU=700MHZ

TCP control: westwood

Scheduler: cfq

Governor: interactive

Change settings: All of the settings are in the 50cleanTWEAKS

/system/xbin/sysctl -w net.ipv4.tcp_congestion_control=westwood (Replace westwood with a new TCP Control)

echo deadline > /sys/block/mmcblk0/queue/scheduler (Internal SD)

echo deadline > /sys/block/mmcblk1/queue/scheduler (External SD)

echo "2 6 10" > /sys/kernel/rt_config/rt_config (Hotplug Settings)

echo 0 > /sys/devices/virtual/misc/fsynccontrol/fsync_enabled (0=off and 1=on)

You can also use Hund app to change these settings: Hotplug, scheduler, and governor. However, you need to check for duplicated commands in the init.d folder..:)

Please feel free to ask any questions and give me feedback...;)

Thanks and enjoy,

LMK
[Asus Transformer TF700] lucius.zen:
Yo what sort of changes have you made to the cfq scheduler. I haven't done any scheduler testing/tweaking for 4.2 yet it would be awesome if you could share your experience in a bit more detail and the specific tweaks you made to make cfq perform better. I made some modifications to the format of the script I have been using for tweaks to make it easy for us to share and create a master script :) I will send you a link so you can download it as soon as I get a chance.
[Asus Transformer TF700] LetMeKnow:
Thanks...:good: I am planning to create a master or universal tweaks for the ROM, internet, and kernel for everyone to use...;) Instead of using ramdisk, I can use the preinit.d script or just plain init.d script...:) I have reserved post #2 for kernel tweaks and explanations and post #3 for ROM tweaks and explanations... I don't have a lot of free time to work on it yet but I will do that. If you like to work with me on these tweaks, I am more than happy to get something like master script that you are working on.. I just want to make our tf700t flying for every user to enjoy...;)

Have you tried my ET yet? I got the best quadrant score on the v1.5, 8049...;)
[Asus Transformer TF700] lucius.zen:
I havent had a chance to apply them yet. I do not want to apply all of them at once however because I want to test them individually.

I checked out your .zip, if I am correct you have made the following changes:

- hotplug config - 0 0 0

- set CPU/GPU freq in cpu1-3

- disable fsync

- custom GPU voltage table

- custom CPU voltage table

- change internal/external scheduler to cfq

Just let me know if you have made any other changes so that I can test everything with my tweaks individually.
[Asus Transformer TF700] LetMeKnow:
You are correct but those are just a setting...:) All the tweaks and a secret ingredients are packed in the ramdisk...;) I can bring them out and convert them into the init.d script format.. It is not a problem and will do that so you can see them easier...:)
[Asus Transformer TF700] lucius.zen:
That would be awesome I figured you had some more stuff packed in there haha. Sorry for the trouble I just really prefer to apply and test tweaks manually one by one. I am a little bit obsessive :p
[Asus Transformer TF700] LetMeKnow:
I still have a few more stuff to test. I will try to do that for you in a few days when I am done with my testing...;)

After no problem for a while, I'm having the rebooting problem again.

Going to reinstall 5.2.2 and try ET 1.5.
[Asus Transformer TF700] LetMeKnow:
I am sorry to hear that...:( Maybe you should stop using the ET....:) You can turn on the journal on your partitions to give more reliability but you will suffer a little less in performance..:) I can create a zip for you to turn on the journal if you want to try it out...

Thanks for the feedback,

LMK
[Asus Transformer TF700] bluewr:
No, it might not be the ET, it could be a bad shut down, while updating, it ran out of power, wasn't paying attention to the battery.
[Asus Transformer TF700] LetMeKnow:
If your device is certainly shutdown while your system is updating, you could corrupt your partitions because you also turn off your Fsync which is another reliability you have it off to gain speed..:) You can try ET v1.5 + Hund v3.4.2 which has the dynamic Fsync to save you when something like that happenning to you....:fingers-crossed:
[Asus Transformer TF700] LetMeKnow:
Another update or wait?

Does anyone want another update? It is a minor update on the quantum and more priority on read over write...:)
[Asus Transformer TF700] Drenus:
I'm always up for another update. :D Two questions: (1) should we always wipe cache and dalvik cache before installing ET updates? (2) how do you measure performance of your updates? I stopped quadrant/etc testing a while back because I didn't find them too useful. I rather relied on whether the tablet seemed laggy or not. But I couldn't really say whether the latest ET was faster/better than the prior version. So I was just wondering if there was some standard tests you run that we could use to give you feedback. And as always, thanks for your work!
[Asus Transformer TF700] LetMeKnow:
Wow, your questions are really made me banging my head against the table...:)

1. This is should be an easy one.. No, it is not necessary but it is a good idea to let your VM rebuilding all your user apps and erase all the unused blocks so your device can access to user apps faster..:) Especially, when you uninstall and reinstall a lot of apps or games...;)

2. This is a tough one...haha. It would be depended on what I want to test. The performance is a general term at least for me that the over all performance is reasonable.. For example, if you have a very fast CPU speed, it does not mean that you don't have lags because something else may a bottle neck of you fast CPU...:) One good example is the I/O speed on our tf700t...:( You and others testers said that quadrant is a useless app but for me it is quick over all testing during tweaking my device. If I am tweaking my CPU speed, I can run a quick quadrant test to see what is the point on my CPU. That number is including the over all of the integer and floating point or arithmetic calculating to stress your CPU... If I want to know more details, then I can antutu or other apps to do a stress test on my CPU... Another number on the quadrant that I use a lot is the I/O number. It is telling me how fast I can access with read and write to my internal SD...:) If I want more details on my test, I can use antutu but it puts a lot of stress on the device for a good 2-3 minutes test. Our device will get hot, haha..:) In the antutu, it gives you a more details how the test is performing. You can look at it and try to improve those area if it is low... I also use SDcard tester for my internal and external SD speed test.. This is the list and depend on what I want to see on the results: speedtest.net, androidbench, SD bench test, and a good practical testing is multitasking with the google play updating and playing game at the same time...There are more apps that I used but they don't give me a consistent results so I stopped using them..:) I hope that it helps...

Edit:

I forget two very important apps that I am using frequently: trickster and cpu spy to monitor my temperature and how my frequencies behaving across the available frequency spectrums... I am working a lot on how to reduce the temperature and save more juice on our device. So those two are my main apps that I am using right now...:) Even though they are not a measuring apps but they are telling me at what frequency that my device using most of the time so I can lower it or change it:D
[Asus Transformer TF700] LetMeKnow:
Hi everyone,

I just requested Hundsbuahs,our kernel developer for the tf700t, to add more I/O schedulers for his kernel. According to my research, the two that hund added in will give us a big boost for the slow I/O. I will run a quick test and see how things are going.

BTW, please stop by Hundsbuahs post and give him some appreciations and thanks for his supports and his time....:good: Here is the link to his post:

Thanks everyone,

[Asus Transformer TF700] berndblb:
Good luck everyone is not very reassuring! :laugh:

I am going to try this on my rom2sd installation with _thatv7.

What's the best way to test it? Quadrant?
[Asus Transformer TF700] LetMeKnow:
Hahaha, if you are running _that v7 from Cromi, sbdags already adds it in his mounting options. You have to test it from _that zip...:)

-Using quadrant and look at the I/O score number for the I/O improvement

-Using SD card tester for Read/Write speed

You may want to run a few tests to have an average numbers...:)

UV Explanations!

[MENTION=4968172]berndblb[/MENTION]

I don't think that I can create a few profiles for you because my setup is different than your setup. The best that I can do is trying to explain about my profile so you have a better understanding what I meant..

The way that my device works is either going to max frequency for performance depending on the modes and dropping down to lowest frequency when it is idle. My device does not use other available frequencies that are supported by the kernel.

For example, if I am in the performance mode and set my CPU at 1.8GHz, my device will go to the max frequency at 1.8GHz when there is a read or write then it will drop down to a minimum frequency when it is done. If it is a light load and does not need a lot of CPU resources, it will drop down to second lowest frequency in one cycle of the timer rate and stays there until the job is done..

For my Under Voltage setting, I only need to find one optimal voltage which give the fastest frequency for my mode and keep the rest of my under voltages as low as possible to save battery. So there are only three modes that I really need to optimize, 1.3G, 1.5G, and 1.8G.. The rest of the UV are very minimal values. These are my UV for the CPU:

### CPU Under Volt!

echo "1350 1280 1220 1155 1090 980 910 860 825 750 720 680 630 610 560 490 340 270 215 185 150 130 85 60 45 40 35 30" > /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table

1220mV for 1.8G, 860mV for 1.5G, and 630mV for 1.3G

My lowest frequency is set at 204MHz and only uses about 85mV when it is idle... Sometime, it goes as low as 51MHz and uses only 45mV...:) I don't know when it is in sleep mode what the frequency that it is in use...:(

You can use these voltages and compare with your own UV settings to see if you can go that low.. I also captured a few screens of my CPU usages for you to see.. I hope that it helps..
[Asus Transformer TF700] berndblb:
Thank you for that, mate! Just to write this post was a lot of work - and I'm afraid mostly wasted on me since there's so much I lack in basic knowledge!

But I'm sure there are other users who will benefit tremendously from it. Directly by implementing your tweaks or indirectly by those parts that sbdags integrates into the rom.

I salute you and thank you! Keep at it!

Is anyone interested in the ET v1.6.. :D
[Asus Transformer TF700] sbdags:
Yes. :)
[Asus Transformer TF700] LetMeKnow:
I will post it up with a new build.prop. I don't know if there are any changes since last time that I gave it to you....;)
[Asus Transformer TF700] sbdags:
I've been removing a lot of tweaks from the buibuild.prop on the TF701T version of CROMi-X with great success. I suspect that the lag after installing play store Apps and also some battery drain can be reduced by not using some of the props.
[Asus Transformer TF700] LetMeKnow:
Thanks for the information. Do you know what tweaks that you removing help the battery drain and the lags from updating play store? Actually, I don't have the dock to test out the drain but my standby is very good...:) I lost less than 1% for about 8 hours of sleep..:good:
[Asus Transformer TF700] sbdags:
Still testing and will be over the next week, but I have reduced the number greatly without hurting performance too much. I'll send you the list in a bit.
[Asus Transformer TF700] LetMeKnow:
That is great and thanks in advance..:good:

BTW, I am thinking to enable the journal on all partitions. What do you think? We will suffer about 300 points on quadrant and 500 points on antutu.. The r/w speed also seems to lower a bit...:(

Update:

My antutu score is around 19500 and 7700 for quadrant with 1.8G CPU, 700M GPU.. That is the optimal setup for the ET v1.6 which is best for multitasking, battery usage, and performance over all..;)
[Asus Transformer TF700] sbdags:
Yes that is what I do in essence in cromi-x installer now.
[Asus Transformer TF700] LetMeKnow:
I will do that for this release and see what testers say...:)

BTW, you should add the 3D tweaks for _that's users in the build.prop or the preinit script. The GPU on the tf700 is a little weak for that high of resolutions.. Please let me know if you need input on that matter...:)
[Asus Transformer TF700] sbdags:
I'm going to try them later ;)

---------- Post added at 07:40 PM ---------- Previous post was at 07:20 PM ----------

Just had a thought - I set all my FPS limits to 0 since the original CROMI - I assumed this turned them off - are you saying that 90 works better than 0? I know Asus sets some of these to 30....
[Asus Transformer TF700] LetMeKnow:
That is a good question and don't know that Asus sets them at 30...:) Also, I am not technical but I am practical. I test them with quadrant and antutu and both report back with the improvement in 3D and a little bit in 2D...;)

Moreover, if you check your underflow status, you see an improvement in that area too. So I think that with the 90 value for FPS is certainly head to the positive direction which is the good news...;) Unless someone has a better method to test it out and I am more than happy to give a try...:good:
[Asus Transformer TF700] LetMeKnow:
Still working on the ET v1.6!

Hi guys and gals,

I am still working on the ET v1.6 and it is getting late here so I have to finish it tomorrow...:( I am very please with this release because there are a lot of improvements comparing to the previous release..:) If you are currently using my ET, you will be even happier with this new version...:good: I will let you give me your feedback and please let me know your user experiences on this ET for further improvements. Thanks in advance..:good:
[Asus Transformer TF700] _that:
You're right that there is little risk to disable the journal on the cache partition - because it is never written to in normal operation anyway (at least on stock and stock-derived ROMs), so there is also zero gain. :)
[Asus Transformer TF700] sbdags:
Yes tried 90 and can confirm it does indeed improve fps :)
