[Tutorial]Sysctl and you, A guide to better preformance and battery life.
- Thread starter Jboxen
- Start date
I cant get root explorer to mount r/w to edit the text why is that i click on it and it does nothing.
ow to set the values that Sysctl will be changing, also done with root explorer. This will be done in the /etc folder. Navigate yourself to the /etc folder and see if you already have a sysctl.conf. If not, click the menu softkey and then click more>new file. Name this new file sysctl.conf . Mount the system RW now and open the file in the text editor again. Now type exaclty these lines into the file. (It's ok to delete what's there if anything and replace it with this.)
vm.swappiness = 0
vm.min_free_kbytes = 4096
vm.dirty_ratio = 90
vm.dirty_background_ratio = 70
vm.vfs_cache_pressure = 1
vm.panic_on_oom = 2
vm.oom_kill_allocating_task = 1
kernel.panic = 5
kernel.shmmax = 2268435456
kernel.shmall = 16777216

This is an awesome tutorial! Thanks so much. Got a quick question, if we use Cache cleaner and have it set to clear cache everyday is that the same thing as entering that terminal command or rebooting the phone?
Oh and I know this is for the D2 but I'm guessing it can work for the X too? Lol

I had been told that even turning your phone off every night will suffice in cleaning out the cache.
Also, in Liberty Settings, there is a "Clear Cache" tickbox. I wonder if you can just check that box and it will be done for you automatically? (and I wonder why we would need to check that box if I was told that just turning off the phone will clean out the cache???)
it womt let me it says you cannont edit this file because the file is system is read only.it wont let me mount r/w
still not Jboxen 
but yours look exactly like my numbers.
but yours look exactly like my numbers. @Jboxen, I just uninstalled the toolbox again, reinstalled it again, and re-entered all the #'s, ran the terminal command again, and all the numbers look right - will you doublecheck?
thanks so much for all your help!

Thank you Jboxen. Now I just have to wait and see if I can notice a increase in battery life.

I have noticed just rebooting every morning keeps my phone running fast and fresh . Haven't tried this stuff yet though.
