[Kyocera Zio M6000] sinisin:
With the recent release of Spz0s rom and Adrynalyne getting this beat over clocked these settings are becoming obsolete. Use at your own discretion.

I recently restored my phone to stock, with basic settings, meaning I did not use any of the settings listed here. I scored a 1013 on a bench with stock everything. Now that I have VTL Launcher as stock again and have everything set back up for me, I'm scoring 1000s and 990s regularly. Again without any of these settings enabled. Which is leading me to believe that a stable system is the fastest thing when it comes to performance and benchmark scores. The settings listed below did help me out, with an unstable system. Now that I am running on a stable system, none of the settings below helped my performance or bench scores, they only hurt them. So these settings below will help anyone with an unstable system to not feel the lag of said unstability. If you try these settings and they don't do anything, or hurt your performance or score, turn them back to stock and revel at how much you rock for having a super stable system! I have also noticed that the app AUTO KILLER MEMORY OPTIMIZER virtually replaces sysctl. If you run AUTO KILLER I would suggest setting sysctl back to stock! I would recommend AUTO KILLER MEMORY OPTIMIZER from the Market to EVERYONE with a Zio. Nice app, set it to Aggressive!

FIRST OFF, THESE SETTINGS ARE ONLY CHANGEABLE IF YOU ARE ROOTED!! If you are not I cannot help you!!

I am making this thread to address performance issues with the Zio. If you have done a benchmark score with just basic settings, it's already apparent to you the Zio is not the best phone. I have found some tweaks to make the phone run faster and score better on benches.

USE THESE SETTINGS AT YOUR OWN RISK. IF YOU SCREW SOMETHING UP, DON'T CRY TO ME.

Stagefright: Stagefright is part of the stock media player that comes disabled on the Zio. Turning on stagefright will increase your benchmark score by a lot, and has also been reported to make Video Playback much better, getting rid of jumpy lagging videos.

You need to make sure you have r/w(read/write) access in your file manager. Root Explorer has r/o(read/only) and r/w. You cannot change any files without r/w access in your file manager.

To Enable Stagefright you open your file explorer(i.e. root explorer, astro, etc.) and navigate to the system folder. Open build.prop in your text editor. Scroll down to where you find stagefright. There are four settings for it grouped together near the bottom of the script. Next to each setting it says =false. You need to edit the false to say true. Once that is done, go up just slightly from that spot, there is also another spot to enable stagefright. Change that to true as well. Also notice that just above this last stagefright script, there is something about the vm.heap and dalvik cache. This is where you change your VM Heap size.

(NOTE: ENABLING THE HTTP SETTING IN STAGEFRIGHT ALLOWS FOR A RICHER HTTP BROWSING EXPERIENCE BUT WILL ALSO PUT A GREEN BAR ON YOUTUBE VIDEOS. KEEPING IT SET TO FALSE WILL AVOID THIS GREEN BAR AND SHOULD NOT AFFECT OVERALL PERFORMANCE!)

VM Heap-Not exactly sure what the technical aspect of it is, but increasing the vm.heap gives the dalvik cache more room to work with, thus making your memory faster. THIS NUMBER SHOULD NOT BE SET BELOW ANDROID DEFAULT WHICH IS 24. And should also not be set above 44. If you want to change this number, add or subtract 4 within the above values, 24-44. This can go down to 16 but you'll see the results and why I said to leave it up pretty fast.

SYSCTL- To edit these settings, open your file explorer, hit the ETC folder. Scroll to bottom and find sysctl.conf, long press and open in text editor. So far I can only say there are three settings here you need to adjust.

To edit SYSCTL settings you must first download and install the app sysctl config from the Market. After you set it up initially it can be uninstalled and leave behind the settings folder for further settings changes by manually editing or you can keep it and just use it to make the changes.

First is MIN FREE KB. This number will not be the same for everyone, although I can tell you setting this number above 4096 seems to slow the system way down. Although you may try any of the following numbers..

1536, 2048, 4096, 5120, 5632, or 6144.

These are the only numbers I would suggest using as they are parameters that came out of the phone itself.

sys/module/lowmemorykiller/parameters. <----DO NOT CHANGE the numbers in this location, they are system defined parameters and are

NOT

to be changed!

The second setting is vfs.cachepressure. I have this set to 10. Default is 50. Basically what I've read about this, it opens more room by setting it lower, leaving more memory free from constantly checking and clearing the cache. Read more here http://xdaforums.com/showthread.php?t=523707&page=12

The Third setting is oom. It's the last value in sysctl.conf and needs to be set to 1 or 0. Instead of your phone starting to kill apps when it's out of memory, it does something else that I didn't quite understand, which is supposed to boost memory performance. Some people are seeing great results with this setting. Some people say it doesn't do anything. Seems to be specific to the user, and I have yet to find anything in common between two users who say this helps. Although bench scores are higher with it set to 1.

For these settings to take effect you must reboot your phone. Changes to these settings are only applied by a reboot, so any time you change anything, REBOOT!

If you do not know how to change settings manually, there are two apps in the market to help. VM Heap Tool will change your VM Heap for you, no need to manually edit if you don't want to. sysctl config is an app that will allow you to easily change the sysctl settings.

There is an App that will change your stagefright settings for you called Blade Buddy. I did not have a good expeience with this program and would suggest that you edit stagefright manually since it's pretty easy with a superuser file manager.

I can say with certainty that turning on stagefright and adjusting and playing with the rest of the settings that your phone will turn in to a beast compared to how it came out of the box.

As far as battery performance goes, I've noticed a 10-15 percent increase(estimated) over the life of a charge(depending on amount of usage and type). I have noticed more battery use. But not so much that these settings wouldn't be worth using. I gave numerous variations of these settings tries over 2 very long months of restarts and three different benchmark programs. Any additional information or discoveries are welcome.

If this helped, please hit Thanks!!

Muchos Gracias to everyone in #openzio as always. Spz0 n Mattix are always a big part of anything I do. They are always nice enough to save me from myself. And much thanks to anyone that helps out with the Zio at all. Lets own this phone!
