[XPERIA X10 Themes and Apps] Eugene1991:
So it seems the most recommended is: Currently trying this out :D

Rubix's minfree setting (20480 blocks x 4 will give you 80MB)

vm.dirty_ratio = 90

vm.dirty_background_ratio = 55

vm.vfs_cache_pressure = 20

This one is for higher performance & battery life:

Min Free KBytes :4096

Dirty Ratio:90

Dirty Background ratio: 70

VFS Cache pressure: 1
[XPERIA X10 Themes and Apps] SErooted:
mmm, vfs cache pressure at 0 i think that means that caches arent reclaimed at all. and if i recall right, cache slows down after starting to get full. so having vfs cache at 0 isnt bad/good. we can go as high as 10000 if wanted. random settings? random settings are what you have when you twist the dial and it lands where it lands. people have their settings cause they chose them. your ignorance is bliss
[XPERIA X10 Themes and Apps] highaltitude:
well, I dont know much about what these settings do, but I found I got way better quadrant scores by not using the settings that were listed previously. My scores jumped by over 200+ I used:

These settings gave me 1354 in Quadrant:

Min Free KBytes :16284

Dirty Ratio:97

Dirty Background ratio: 62

VFS Cache pressure: 25

These gave me 620 in Quadrant:

Min Free KBytes :16284

Dirty Ratio:95

Dirty Background ratio: 60

VFS Cache pressure: 50

The settings given by the OP gave me 1124:

Min Free KBytes :16284

Dirty Ratio: 5

Dirty Background ratio: 3

VFS Cache pressure: 0

Certainly some different results. Just wanted to share. Not sure what the optimum is but...
[XPERIA X10 Themes and Apps] Realorasz:
It seems that vfs cache pressure is what makes the most difference, look at the above post. I think it may have a sweet spot in the tens or twenties.
[XPERIA X10 Themes and Apps] burshturs:
Yes please. And by the way just give a try and let us know what do you think.
[XPERIA X10 Themes and Apps] ooidort:
I honestly do not see any difference in real-life performance nor in Quadrant or Linpack scores after applying any of the settings in this thread. Am I doing something wrong...?
[XPERIA X10 Themes and Apps] burshturs:
Which rom are you running?
[XPERIA X10 Themes and Apps] burshturs:
Thanks for your words. Just to let you guys know I set the vfs cache pressure to1 instead of zero and the performance is about the same.

Cleaned and JIT-enabled stock 2.1.
[XPERIA X10 Themes and Apps] burshturs:
I think these settings wont work on 2.1 roms. I have only tested it with Froyo roms.
[XPERIA X10 Themes and Apps] Eugene1991:
No wonder I don't feel any boost then, Im on Go3asy's Honeycomb Look Eclair 2.1 ROM..
[XPERIA X10 Themes and Apps] highaltitude:
I am running FreeX10 2.2 mixed with Cyanogen
[XPERIA X10 Themes and Apps] Realorasz:
No, I'm pretty sure it works with 2.1... It gave mine a pretty big boost. I'm on go3asy's rom as well.

EDIT: Just tested it, it at least does reduce a 2.1 ROM's boot time. I disabled it then rebooted, timed it, then re-enabled it and rebooted, got like 12 seconds shaved off. Off to ready to rock in <30 seconds. Before it i was getting around 42 43 seconds. The smooth as an iPhone, well, that's rather dependant on the person i guess, although it does run very smooth animation to my eyes.
[XPERIA X10 Themes and Apps] Eugene1991:
So which setting did you follow can you share it with me? Since we're using the same ROM.
[XPERIA X10 Themes and Apps] Realorasz:
Min Free KBytes :4096

Dirty Ratio:90

Dirty Background ratio: 70

VFS Cache pressure: 1

EDIT: another good way you could keep it running smooth is advanced task killer. Put all your widget apps on ignore list, plus any system apps that are necessary to the phone running, etc. and put the ATK widget on your main screen, and click it every chance you get(obviously not EVERY time you see it, though.) That'll help a bunch, cus it frees up processor power and momory from background processes.
[XPERIA X10 Themes and Apps] chiefy009:
Task killers make your phone use more battery and run worse, Google it and see for yourself.

Does anyone know what they are doing with this app ? It seems up till now everything has been random trial and error

sent from my Commodore 64
[XPERIA X10 Themes and Apps] Realorasz:
It shuts down processes of apps you started which run in the background, such as mixzing while you're browsing the web. Android doesn't automatically kill that. That's also why there are ignore lists. Use them. Kill only things that really dont need to be running, android-born or not, and things you opened. Everything else goes on the ignore list, a reason task killers are for experienced android users. A main reason they actually help the phone run better is because in killing the stuff that doesnt need to be running but still is, you free up ram and lighten the load on the cpu.

EDIT: For example, when I back button out of Dolphin Browser, It's not automatically shut down. I have to actually tell Dolphin to shut down. Same with mixzing, i may have it paused, but my settings enable the headset control. SO when i hit the button, it starts the music again. However, when i click the ATK widget, then after that the headset button, nothing happens.
[XPERIA X10 Themes and Apps] chiefy009:
Android kills the services automatically and is made to give the impression that you never close anything. There had been enough research done by lots of people tasks killers do not benefit your phone. An app that watchers for runaway apps and allows you to kill that specific app is better for your phone. As I said Google it and see for yourself you will find advanced users won't touch task killers, and if you Google why you will see

Edit --- the developer of android is documented in the press stating he hates task killers

i definatly agree with the fact that task killers are not really neccessary .. if ur on the stock rom ( i am as well) jus pop a shortcut to 'running services' and pop in there after u use a program and stop the task urself, it might take a few extra seconds but it adds 0 pressure on ur phones performance battery etc, because it is a shortcut vs a widget(which most task killers have)

im not a dev or a pro by any means, but i can definatly tell the difference in with this program iin boot time, and general responsiveness. i also feel like my battery has been lasting longer ( heavy usage for a full day and i got 35% left, where before my phone would have died hours ago)

im also running a cleaned, jitted, x recoveried stock 2.1 and running with these:

Min free - 2048

Drty ratio – 90

Drty bckrnd ratio – 55

Vfs cache pressure – 20

my phone feels fantastic .. once again i am not a pro or a developer, but most of us arent, jus read as much as you can before taking action, and play around with it!
[XPERIA X10 Themes and Apps] burshturs:
Taskillers are not the best way to keep free ram. It will drain your battery since android will reopen the closed apps anyway.

Something good to try is tweaking the internal memory manager.

If you are rooted you can try Auto Memory Manager from the market. This is not a taskiller. It allows you to increase/decrease memory tresholds.

I suggest to use "Agresive" to have more free ram.

Can some one post balanced set for Z`s Beta4 rom 2.2.1?

Thanks
[XPERIA X10 Themes and Apps] mrljlamon:
the only apps that re open are needed system apps, or apps that keep running and using data, or bloatware apps.

apps like vignette, or twitter (which will not re open if ur not signed in or using background updates), or root explorer, titanium backup etc, will not re open on their own. as they are not needed

i use task killer, but only, and i mean only..and very periodically to close apps like those one by one if i know im not gonna open them again. and i make sure i close task manager out completely when im done. and apps that i know i use all the time are in my ignore list (most of my apps are ignored: setcpu, titanium, adw) just to make sure i dont close them by accident. i guess i COULD just use the built in app to force stop tho in my case.

however that autokill stuff, def not good. i agree with u that there are better ways to free ram.

i meant not to be rude when i phrased this. so i hope offense was not taken. some settings actually do show performance change and others really not so much. at current i have removed sysctl from my rom. and actually have low quad scores, slow start up/shutdown. but a higher mflops score back to where i ran previous without it. battery life has once again started to drain like mad and am a little frustrated.. but then again i also have everything ruinning. gps, gps assist, wifi, everything that doesnt always need to run i have running. part of problem for drain. once i get back to a fresh install of everything. i will post my results with three different sysctl settings and let you know what i have found to work best for current rom and personal preference.
[XPERIA X10 Themes and Apps] burshturs:
You should also see other signs of improvement appart from benchmark scores. Appart from responsiveness I have found that the settings posted in the first post also improve scrolling a lot and 3d games are visually more smooth even if the linpack score is a bit lower (less than 2 points)

[XPERIA X10 Themes and Apps] a.monteiro:
I'm starting to think Quadrant and limpack benchmarks mean nothing to the user experience, that data2sd tweak can give you high scores but makes the phone lag a lot

I've used this sysctl tweak on wolfbreak's CM6.1.3 rom for a few days, tryed a few different settings and noticed little to no difference in speed and battery performance with the ARC launcher, then i've changed to Launcher Pro and the difference was far more noticeable, phone became much more fluid and responsive.
[XPERIA X10 Themes and Apps] Bwyan Benton:
Ive been saying that for a while now. Linpack and Quadrant scores mean NOTHING! It's crazy how many people are trying to get a higher and higher number instead of just paying attention to how smooth and fast there ROM already is.

Sooooooo true........everytime I try quadrant my score is anywhere between 950-1350...... and that's with no changes to my phone.......the benchmark is pointless......don't need it to tell you how fast yer own phone feels
[XPERIA X10 Themes and Apps] nytral:
Running Wolfbreak CM6.1.3 (froyo), these settings kill battery so much that it won't charge on USB.. and I have to apply them with sysctl -p.

Have any of you actually checked with "sysctl -a | grep vm" that the settings were actually applied? In my case, they aren't, even with sysctl config set on boot. When I force them, go to top of post.. :D

Those are the settings suggested by wolfbreak for his rom. My settings are a little bit more risky and at least in the rom i am using ( [ROM] CM 6.1.3 V4.5.7 with Camcorder [19-03-11] [Tweaked+Theme+Extras] ) the settings in the 1st post give me the fastest performance.

I must admit that those settings caused that my phone ramdomly rebooted sometimes, however, after enabling compache this issue completely went away.

Hello, well, maybe I am a compleet noob about the forum, but I followed some threads and applied some settings and apps.

I'll first give some stats from my X10i about the firmware and Mod Version:

Cyanogen 6.1.3 Gingerbread[V01] With Honeycomb theme.

2.1.58 Baseband.

I've applied Data2SD on a 8GB Class 4 card and my Sysctl settings are:

4096

90

70

10

My quadrant score is 2444.

Further apps are Watchdog and Autokiller.

But what is Linpack for? If I run a benchmark, this will come out:

MFLOPS: 31.839

Time: 2.62 sec

Norm Res: 5.68

Precision: 2.220446049250310E-16

Battery life increased like heaven since the new settings. But I'm really not familliar with the Linpack.

Will my phone get a higher quadrant score if I got a higher SD class then class 4?

And how much memory will data2SD take from your card, or is there also an app for that?

Thanks guys!

Love the forum!!
[XPERIA X10 Themes and Apps] Lord Takyon:
Your quadrant score is impressive, I'm not prepared to go that experimental as I need stability.

Your linpack is slightly lower than mine, I average around 34. I think it is more of a CPU test than anything.

Benchmarks are not that relevant when it comes to actual performance, they do not always correlate with each other.

How to in Linux

Hai

I am using an Ubuntu desktop...and might am interested in knowing hw to do it in Linux?

[Android Software Development] cj chitwood:
I wish I could help with that. While I use Linux too (Ubuntu, I think, on my laptop and Sabayon on my desktop), and used to use it as my primary OS, I do not know enough about it to do this. For starters, I've never gotten a decent working load of Google Earth on my laptop in Linux. When I was researching this, I found that 99% of what I found was based in Windows, and I was short on time so trying things in Linux was an unaffordable luxury. Everything takes me forever in Linux because I have to learn it first, and then start screwing with it.

For starters, though, you have to get ADB working, and then port forwarding the GPS to the phone's USB (done through ADB). From that point, I think Linux might *just* be able to handle getting the data visible to apps like Google Earth natively. I would start my search with "usb-to-telnet forwarding". Or "accessing USB with telnet", since really once you do the ADB forward, the phone is sending data direct to the USB port.

Edit: Of course, you'll also still need ShareGPS on the phone... I think...

I really don't know enough though to be able to provide the help I'm thinking you need/want, but hopefully this can at least get you started on the right track. If you figure it out, please post back to this thread...

Cheers,

CJ Chitwood

Linux Solutions???

I am going to dive into getting this working with Ubuntu on my EeePC. Right off the bat I'm thinking why not send the GPS to the netbook over bluetooth and use use the USB tether for the internet access? I'll see what my untrained brain can come up with.

Thanks for the post on this issue, I've been looking into this for 2 years.
[Android Software Development] cj chitwood:
Right, that should work if your Asus can receive GPS over bluetooth, and the USB tether for internet would save you a little on battery as you could kill the WiFi on both devices. My only problem was that my laptop did not have a bluetooth transceiver on it, so I was stuck doing it the bobo way. Story of my life, really ;)

Glad it helped!
[Android Software Development] Fietspomp:
Thank you for this guide, I used some other applications though.

For my HD2 (running on Android 2.3.5) I used BlueNMEA, you can get it from the Android Market

I connected my phone with my laptop (running Win. 7), installed SDK and used ADB).

With ADB I used the commands from the BlueNMEA guide:

Using BlueNMEA over USB
-----------------------

Needs the Android SDK.

Connect your phone to a computer with the USB data cable. On the
computer, type "adb forward tcp:4352 tcp:4352". Now you can get NMEA
data by connecting to TCP 4352 on your computer.

For virtual ports I used HW VSP, quite simple to setup, I used COM9, typed 127.0.0.1 as address and the port 4352. It creates a service so this is a 1 time job.

At first I used GPSGate, but this didn't work with BlueNMEA.

GPSGate works with ShareGPS, same principle I guess.

For testing my GPS on my laptop I use OpenCPN, it shows my location perfectly.

The phone is also very stable, no problems at all.

The internet part doesn't concern me, because I have internet at my laptop :-).

I've been searching for a method to use my Android as a GPS mouse and I found this, thought I'd share my findings with you.

The fastest way to do this is via Bluetooth I think, but my laptop has no Bluetooth, ordered one @ Ebay for 5$, hope this saves me all the hassle.

The only thing I'm wondering, since I'm not familiar with Android SDK, is the ADB forwarding still alive after a reboot?

BTW, for people still searching for a Linux guide: http://sharedroid.jillybunch.com/user_linux.html
[Android Software Development] cj chitwood:
Thank you very much for that! Nicely informative.

AFAIK, the adb forward is gone after a phone reboot. However, I've never actually tested it. I've also not looked for a way to undo it...
[Android Software Development] Fietspomp:
I've fooled around a bit with the phone, every time I disconnect/connect I have to forward the port using ADB, ow well, I'll use Bluetooth as soon as I have my dongle.

The best part is this works, so I'm sure it will also work with Bluetooth.

I know for Windows Mobile it is possible to tether GPS through activesync,

which I used for my HD2 when it was stock Windows Mobile.

I use this when I'm at sea, I'm a sailor so it's nice to track my course.
