Title:
Heavy Disk I/O harms desktop responsiveness
Status in linux package in Ubuntu:
Incomplete
Bug description:
Binary package hint: linux-source-2.6.22
When compared with 2.6.15 in feisty, heavy disk I/O causes increased
iowait times and affects desktop responsiveness in 2.6.22
this appears to be a regression from 2.6.15 where iowait is much lower
and desktop responsiveness is unaffected with the same I/O load
Easy to reproduce with tracker - index the same set of files with
2.6.15 kernel and 2.6.22 kernel and the difference in desktop
responsiveness is massive
I have not confirmed if a non-tracker process which does heavy disk
i/o (especially writing) replicates this yet - will do further
investigation soon
