[Nexus 10 Original Android Development] brees75:
Just thought I would share some tweaks that work with this kernel really well. These will tune androids memory management, increase io, make the system smoother and increase overall responsiveness. You will notice more free ram and better performance over time. Just coy and paste into the bottom of an existing init.d script found in system/etc/init.d folder then reboot and clear cache/dalvik.
