[Nook Color General] mr72:
That can easily be done with a script. Maybe I will try my hand at it and see how it works.

FWIW, I plan to research some of this and determine precisely what it is doing besides the default. I did a lot of this kind of work with a linux networking appliance that I developed for at my last job.

These are also in sysctl.conf. You could just add these lines, in addition to the ones you listed above:

vm.min_free_kbytes = 4096

vm.dirty_ratio = 90

vm.dirty_background_ratio = 70

vm.vfs_cache_pressure = 1

vm.oom_kill_allocating_task = 1

These can be done by editing build.prop manually.

you want:

dalvik.vm.heapsize=32m

wifi.supplicant_scan_interval=300

(you say the others are not used)

These, I am guessing, are similar or in the similar vein as the V6Supercharger script.

Note the heapsize 92m is an overwrite of your other suggested setting from above.

In my guide, I shared my settings which are similar, but I don't go past 1200. Tweaking the voltages down will probably improve your battery life.

I am going to try the tweaks for build.prop and sysctl.conf.
[Nook Color General] adamdelozier:
thanks for the detail. I am the type to try and ask questions later. Tats how I learn best! Any improvements you can make give us all a better experience.
[Nook Color General] bobtidey:
Interesting thread.

There is also a sysctl config app in the market that allows tweaking of the values.

For those that like to play with fire

from Terminal

su

sysctl -a > /sdcard/sysconfig.txt

will create a dump of all the known current values that the kernel is using.
[Nook Color General] mr72:
Well, most of the sysctl.conf and build.prop stuff is included in the ROM, and furthermore will likely be overwritten when you update the ROM, I would think.

And while I really like the V6Spercharger script, I think combining just the things it does for Nook Color, along with some of these things that make sense, all into one script, would really help. I might try my hand at this and see how it goes. This is all routine stuff for shell scripts.
[Nook Color General] adamdelozier:
If you can do it great! In the mean time, however conflicting the info may be, I will stick with it, because it sure is working damn good on both my devices!
[Nook Color General] mr72:
I am not disputing that it works! :)

I looked into the V6 Supercharger script, and it appears to be trying to be all things to all people, which makes it perhaps overkill for the NC. I might try and make a stripped version of it. My shell scripting is not exactly stellar.

I tell you what, this would all be a breeze to do in ruby. Do we have ruby working well on Android yet? I can't remember. If it was ruby, I could have the whole thing done in no time.
[Nook Color General] adamdelozier:
Lol! I guess I wish I knew what ruby is?! I really want to learn programming and scripting on android. I just don't have enough time in the day with a 7 year old, 3 month old, and a pita job...not too mention the wife!! Haha. I would be more than happy to help test anything you can come up with. I may even try something myself if I can squeeze it in!
[Nook Color General] ohshaith55:
i can't attest to the ui smoothness yet but the wifi changes are insane... in my room my computer maxes out my broadband speed over wifi(30mbps) and i was getting around 15 on my nook(nothing to complain about) and 3mbps maximum on my galaxy nexus which apparently has a very low power wifi chip. i am now getting around 25 on my nook and 12 on my gnex. this is exactly what i've needed. i know you didnt find the tweaks but tremendous thanks for passing this on to us :D
[Nook Color General] adamdelozier:
glad it worked for ya. Don't forget to hit that thanks button ;-)
[Nook Color General] mateorod:
If you are willing to put the packages into your davlik cache you can get Ruby through the Botbrew package manager. I know nothing about nothing, but it works for imagemagick and gcc.if you need dependencies to run, there is a growing list of available packages through opkg.

Inportb has done some cool stuff...
[Nook Color General] ponyboy82:
This is great, I am going to try this as soon as I can. Wifi always seems a little wonky for me.

Along with the previous sentiments - it would be great to package this up in a script or app or something. I don't know if it would be possible to bundle it into the CM9 builds, but that would be even better.
[Nook Color General] mr72:
I am working on a script to do the build.prop and sysctl.conf changes. I'll leave the memory manager stuff to the V6 Supercharger.
[Nook Color General] mr72:
Fwiw I have had a number of hard crashes, nook dies while asleep even for just one minute, since making these changes. I didn't notice any speed improvements. So I plan to study this some more for my own use. I think the network settings are a good idea but I'm not sure the vm tweaks are worth it.
[Nook Color General] mr72:
Here's what I'm trying now, hopefully deals with the crashes:

build.prop:

wifi.supplicant_scan_interval=300

davlik.vm.heapsize=92m

davlik.vm.heapstartsize=5m

davlik.vm.heapgrowthlimit=32m

sysctl.conf:

# Changes added for network tweaking

net.ipv4.tcp_ecn=0

net.ipv4.route.flush = 1

net.ipv4.tcp_rfc1337 = 1

net.ipv4.ip_no_pmtu_disc = 0

net.ipv4.tcp_sack = 1

net.ipv4.tcp_fack = 1

net.ipv4.tcp_window_scaling = 1

net.ipv4.tcp_timestamps = 1

net.ipv4.tcp_rmem = 4096 39000 187000

net.ipv4.tcp_wmem = 4096 39000 187000

net.ipv4.tcp_mem = 187000 187000 187000

net.ipv4.tcp_no_metrics_save = 1

net.ipv4.tcp_moderate_rcvbuf = 1

# Changes added for virtual memory tweaking

vm.min_free_kbytes = 4096

vm.dirty_ratio = 90

vm.dirty_background_ratio = 55

vm.vfs_cache_pressure = 20

vm.oom_kill_allocating_task = 1

and run the V6 Supercharger for the minfree settings (option 9)
[Nook Color General] adamdelozier:
Hey...just as an fyi...this is the link to the epic cm9 blog http://epiccm.blogspot.com/p/cm9-status.html

they show on the latest alpha release some of the VM.dalvik tweaks are now being built into the cm9 releases for the epic. I have not looked yet to see if these are specific to the epic or coming from upstream.
[Nook Color General] mr72:
That's very interesting. I would think those settings in particular are likely device-specific, but it is good to know that some of these are making it into the CM repo. Probably will also happen for the NC.

However, I can verify that these settings were neither default nor automatically set by the CM7.20 build I am running, and I suspect they are not set for CM7.10 either. So for the NC on CM7, these are likely different.

Whether they are a good idea or not, I don't know.
[Nook Color General] swaaye:
I put some tweaks into sysctl.conf but they don't appear to be applied on boot. Specifically,

net.ipv4.tcp_wmem = 4096 16384 131072

net.ipv4.tcp_rmem = 4096 87380 524288

Anyone else verify if sysctl.conf is being used on boot? CM7.2 here. I see the init.d script but I don't know how to figure out if those are enabled on Android. Running sysctl -p as superuser definitely works.
[Nook Color General] mr72:
I don't know if they are loaded on boot. I will look into it once I get some time.

On a slightly different note, I have gone a full day with the settings above without a crash, which is about 3x as long as it went before. The vm.dirty_background_ratio = 55 and vm.vfs_cache_pressure = 20 seem to be the difference maker, so far.
[Nook Color General] swaaye:
BTW it looks like cycling wifi resets tcp options to defaults.
[Nook Color General] tonyp:
Interesting thread, gonna go and play with some values, too.
[Nook Color General] irisclara:
So what's the word on this. Has anyone written a script for the non-V6 parts? I'm really interested in trying the wifi tweaks. Are they being incorporated into CM 7.2 or Mirage? Do the changes stick or do they need reset? I'm thinking about just trying what mr72 posted but figured I'd ask for updates first.
[Nook Color General] irisclara:
Ok, I did the first two parts of mr72's modified tweak and seem to be getting better wifi reception and speed. I didn't do the virtual memory part because I don't feel that I need it. My Nook is totally rockin'.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Scythe024:
So about 2 days ago I noticed my LTE spears drop drastically down to 120kbps with no warning say all. Called AT&T to complain and they said I am just over 2gb, but there's no mark on the account and I am far from being throttle. Turned out to be a error with the system causing a lot of people to get throttled a lot earlier then they should have. Since they haven't been able to fix the issue and had no idea when it would be fixed they basically tools me "your ****ed, but we will credit you money back for the service we couldn't provided." Some of you who got thorttled without a message should check your speeds now or call AT&T and make a stink about it.

TL/DR: att bug accidently throttled people before the cap, now fixed

[Xoom General] wes_s:
http://db.tt/5NnxsW3M

I think thats it, I'm not sure. The package name as you'll see isn't "Motocast.apk"

but its the only thing that made sense since there isn't an apk in there with that name.
[Xoom General] Cubanluke88:
Thats definitely it, thank you for sharing!

Now I need to figure out how to get it to work. A simple apk install was a no-go and dropping it in /system/app didn't work either.

Gives me something to do today I guess :)

Any chance you wouldn't mind doing a titanium backup of motocast and sharing the 3 files?

Here's how to get 'adb remount' to work:

Download this file (right click and save as, save it wherever you keep adb).

Type all of this:

1. adb shell

3. mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system

4. exit

5. adb push local.prop /data/

6. adb reboot

7. adb remount (once the reboot is complete)

That should get it going. I've sent my local.prop to Dan Rosenberg, hopefully he'll include it in his root method.

[Nexus S Q&A, Help & Troubleshooting] blackhemi4x4:
I went to Nexus S from my Captivate for two reasons, GPS and lack of updates.

Directly from google themselves...

http://www.google.com/phone/detail/nexus-s

Nexus S is the next generation of Nexus devices co-developed by Google and Samsung.

Nexus S comes pre-installed with the latest Google apps and has features like true multi-tasking, Wi-Fi hotspot, Internet Calling, Near-Field Communication (NFC) support, and full web browsing.

With this device, users will be the first to receive software upgrades and new Google mobile apps as soon as they become available

.

Now that I see other NON google devices coming out before I get the official, Im a little upset.

If I were to hold them to what they say, they have lied. False advertisment. I love my phone, but seriously Google, where are your priorities?
[Nexus S Q&A, Help & Troubleshooting] Crittias:
Some folks are theorizing that the official ICS ROM for 9020A has been delayed in order to fix the wonky search button bug that sometimes happens in weak 3G areas. Having experienced this bug, one can only hope they're right.
[Nexus S Q&A, Help & Troubleshooting] bozzykid:
That can't be fixed. It is a hardware defect. Google already adjusted the tolerances as much as they could in the latest Gingerbread update. Anyone thinking they are holding up ICS because of a hardware bug that Google has already addressed is probably misinformed.
[HTC Sensation] aiwapro:
I have noticed the higher latency for sure on the ICS ROMs. I tried ExtremeSensation and InsertCoin, and had the same issue with both. I was around 85ms on GB, and around 160ms, or higher on ICS. I tried stock radios/RILs on ICS as well, and the issue persisted.

This needs to get fixed. Everyone seems to be overlooking it, but several people have said they have the same problem.
[HTC Sensation] matt95:
not the biggest problem in the world...you can live with it...for now
[HTC Sensation] samklee:
Yeah. I noticed that too. For me, I typically get around 45-55ms on gingerbread. Ics measures around 110-120. Not a deal breaker but annoying for sure
[HTC Sensation] aiwapro:
Yeah, it's almost a deal breaker for me. I have my older MyTouch 4G sitting right here next to me, and it's latency and speed is fine. It's signal does not fluctuate either, like this new Sensation does on ICS.
[HTC Sensation] BAleR:
55??? Mines terrible, 280+ and sometimes it will just sit there, then say my ping is 1500!!

Yeah, I went back to a Gingerbread ROM, and all was well. Not sure what's up with Ice Cream Sandwich ROMs.
[HTC Sensation] RareHare:
I have slow pings with a Moto G that I bought a couple of months ago. I had a suspicion that the pings might be slow even before I bought it. So I tested, and as you can see from http://xdaforums.com/showthread.php?p=51354213#post51354213, my pings are slow too.

There are two problems with the pings:

mean delay

variance of delay

Both are excessive. Both of these are problematic for certain types of application. Both of these are things that easy to not-get-wrong by a software developer with experience in computer networking. Makes one wonder.

What worries me is that the communication path of general Android applications might suffer the same deficiencies.

Can anyone ping their device and check the delay? Over Wifi with strong signal, you should be getting sub 10 ms times, easily.

Seriously?? You're bumping a thread that is almost 1 year old; WL must have gone through loads of changes, and maybe the option isn't even in the same place anymore, and if you're still having issues, and bought the app, you're more than eligible to email the developer to report the issue.
