Code review comment for lp:~vanvugt/mir/predictive-bypass-2

Note: If you are thinking about doing any testing on desktop, remember to add:
   usbhid.mousepoll=1
to your kernel command line.

That will reduce your mouse latency from 8ms to 1ms, which becomes quite noticeable when you're on the bleeding edge of performance. Having your mouse configured for lower latency also means it's then easier to see improvements in Mir's performance (like this branch), without having what you see clouded by high latency kernel events.
