[SCRIPT] The Best RAM Optimization

---

Hello,

I just try this on my Asus Transformer and it seem to make a big different on the tablet smoothness.

Before when I either wake up the TF or running allot of program, it would lag allot. After the ram tweak, I can said it does make a different. Even after I had almost fill my memory up to 90%, opening new programs and swapping screen is fast. Android does a decent amount of work and return my memory back to 150 (and up) with the OOM Kill task. It did not cure my SOD problem.

I am current running the ram optimization with no other ram optimizer or task killer.

Here my TF configuration:

Prime 1.5, Netformer 1.5 @ 1.5GHZ, SD Boost, and Script Ram Optimization. The link is below. Check it out and let me know how it goes on your transformer. As always, make a nano backup before the tweak.

Hi, if you're running prime 1.5 it has support for sysctl changes built in. By using /system/etc/sysctl.conf_default as a guide, simply put the desired settings into the /system/etc/sysctl.conf file and these will be applied on reboot by the 04sysctl init.d script that's already in the rom.

Or just use the script for the post above, it should work fine too.

nice work !

By the way, what is SD Boost?

can i use this tweak with the netformer kernel and stock rom?

The default settings for I/O is really slow when it comes to SD r/w. With SD Boost app on market, it'll tweak the I/O parameters on boot. If you're running Prime, then it is already tweaked for you and is permanent.

But those files can be applied on stock rom with root and Kernel netformer 1.5 or i can fall in some issue if i don't have prime 1.5 installed into TF?

Apps like that or SD Speed Increase should be fine with just a rooted device at minimum.

and the RAM tweak? if i apply it with CWM on the stock rom (as i have done with wpa_supplicant to turn on Ad-Hoc connections) it's ok or i can have issues?

Here is what Roach2010 already has in the kernel by default:

[taken from the /system/etc/sysctl.conf_default file in PRIME v1.5]
NOTE: only the values that relate to what is in the script that the OP links to

vm.dirty_background_ratio = 5
vm.dirty_ratio = 20
vm.dirty_writeback_centisecs = 500
vm.dirty_expire_centisecs = 200
vm.swappiness = 60
vm.vfs_cache_pressure = 100

Here are the values to place into the /system/etc/sysctl.conf file that Roach2010 mentions above:

NOTE: these are the replaced values that relate to the script the OP links to

vm.dirty_background_ratio = 5
vm.dirty_ratio = 90
vm.dirty_writeback_centisecs = 1000
vm.dirty_expire_centisecs = 500
vm.swappiness = 50
vm.vfs_cache_pressure = 10

Looks to be similar to this app => https://market.android.com/details?i...=search_result
