Bug Description

Mir is spending around 8% of its time in __android_log_print() according to callgrind. That's while I was trying to stress the input system. This is due to the *printf functions that lay underneath.

That number is from a desktop with a single pointer (mouse). I expect it could be a higher percentage on touch where the input processing overhead is greater, and the graphics drivers are also related to Android.
