Thanks jboxen for the reply!

Has anybody tried the Rubix Liberty swap settings from the imoseyon link?

If you only do the first part of the post (the settings in liberty toolbox) will you still get the increase without having to reboot your phone daily?

No you will still need to reboot.

when you say reboot, do you mean to go into clockwork mod and choose "reboot", or just turn my phone off and on?

I turn my phone off every night, and just turn it back on in the morning. Is that sufficient for the "reboot" you're talking about? If I just enter the numbers in the Sysctl field on the toolbox will I see the benefits of battery life as well?

(thank you for this thread!)

Yes that is sufficient and I don't know.

OK great, thank you

I meant that if I just change the fields in my "Liberty Settings"/Systctl Configuration to the numbers in the OP:

Sysctl Supprt: Check
Min Free KBytes: 4096
Dirty Ratio: 90
Dirty Background Ratio: 70
VFS Cache Pressure: 1
Oom Allocating Task: Check


will I need to also do the root explorer / terminal tweaks to gain the benefit?

thanks again for your help!

Hey guys, not saying your late to the party here, but I have a great thread going over on droidxforums.com that I started on Jan 15 Liberty 1.0 and Syssctl Config
Check it out, there are a lot of great posts there.

Mod Edit: Removed Blog Link

Enjoy

I don't know how beneficial the extra tweaks are. I only took the info off of that blog.

Anyone using wireless tether AND this sysctl setup? I set this up successfully last night, used the first method. Most things seem normal, but wireless tether is disconnecting internet every 5 minutes. It's actually staying tethered, just keeps flipping to "limited access", so no internet. I just disconnect and reconnect and all is well.

Any ideas?

@Jboxen
I don't know if the new values are accepted. I downloaded a new version of the toolbox from the market, and changed the values as indicated in the Sysctl Config.

(also, the sysctl support is checked, and the Oom Allocating Task is also still checked)

After reboot, the numbers "stuck", and are still there in SysConfig settings, but here is what I got after running the command in the terminal:

that doesn't look right (to me), because the only number I recognize is the 4096. Can you help decypher this for me?

thanks to all~

I'm not Jboxen, but on first blush I'd say that they didnt stick, at least not completely. the vfs_cache__pressure should be 1, dirty_background_ratio should be 70 and dirty_ratio should be 90. I guess I'd say try again through the settings, and if that doesnt do it, try through the terminal.

hope that helps...

hm.
I didn't change anything, just re-ran the terminal command, and got different numbers:

I went in with root explorer to look at data/liberty, and made sure the sysctl was activated (with a 1,not 0).

I'm not real confident writing code/commands in root explorer to change these, any idea why the sysctl config isn't taking the new numbers in toolbox? I'm confused because it has obviously accepted the 4096 change, but not the other numbers I entered in the toolbox.

Or how my numbers have changed from one screenshot to the next without me changing anything?

If youve updated jrummys oc app, it contains sysctl which may cause issues with changing settings manually.

The overclocking feature in my Liberty 1.5 isn't enabled, but I'm running QuickClock. Would that maybe cause the same issues?

Should I disable QuickClock, or can these two programs interact and run at the same time?

I'm talking about Jrummy's Droid Overclock App from the market. Under advanced settings he has sysctl settings in there now too.
