#1 Custom Kernels
*Credit to @joojoobee666
*The first performance tip is to install a custom kernel. Follow the link below for info on the different kernels available. My recommendation is :
*CPU Governor = Ktoonservative
*I/O Scheduler = BFQ
*Kernel 1.3 GHz OC.
*You can use any OC Kernel that you want, but users have reported that the 1.4 GHz kernels do not boot on the RAZRs.
#2 Custom Minfree Values
*On Lollipop, you need at least 200 MB of free RAM in order to have decent performance. Here are my minfree values, that give me 300-400 MB of free RAM most of the time.
* Foreground App = 48 MB
* Visible App = 60 MB
* Secondary Server = 72 MB
* Hidden App = 84 MB
* Content Provider = 96 MB
* Empty App = 300 MB

*Some users have reported performance improvements with this mod. What to enable/disable will vary per device. I recommended reading the whole thread to decide what options to choose.
#4 Build.Prop Tweaks
*Paste all of these tweaks in the build.prop file, located in the /system/build.prop directory.
*These are the only worthwhile tweaks that I use on Lollipop ROMs.
