[Bug 131094] Re: Heavy Disk I/O harms desktop responsiveness

[Bogdan Gribincea]

I'm running a kernel compiled with:
CONFIG_HZ_1000=y
CONFIG_HZ=1000

Also using "elevator=anticipatory" boot param.
Everything is running much smoother now. Still getting some random stuttering but only under very heavy loads and they only last about 500ms or thereabouts.
Until yesterday I had the default Jaunty kernel, just using the anticipatory elevator and the desktop was much snappier than using CFQ under heavy I/O loads.
The 1000hz option doesn't seem to help as much but I have yet to test CFQ with 1000hz
