This is how I setup my rom after flash, and device is working very well with 52 installed apps :)
1. Configure settings
-Go to wifi and disable scanning always on
-Open mobile network and chose 2G (use 3G only when you need it)
-Go to more and then to mobile broadcasts and disable all (when it enabled, consume RAM)
-configure sound,display, and interface... As you want :)
-go to accounts and disable sync which you don't need.
-go to About and taping on blablabla, you know to enable Developer options and rom performance.
-Go to developer options set all animations(you have three) to 0.5
-Performance??
-you don't need it, I will show you in next step. ;)
2. Install&Configure TricksterMod
-For cpu freq the best is to set device default, like on stock rom, don't forget to press Lock freq.
-Minfree setup
-8mb
-16mb
-21mb
-31mb
-38mb
-46mb
-Syscontrol setup
-Set swappiness to 60
-Set vm.pressure to 40
-Gpu freq
-That is your choice min freq will increase battery life, but some laggs is possible, max freq will drain battery faster, but there is less possibility to have lag.
-Install&Configure Greenify
-You already know :) Hibernate what you want expect Alarm clock, messahing apps, trickster mod, etc.
More soon :)
