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

[Jarkko Lietolahti]

I'm also suffering from the same issue (slow hd i/o).

I also run the SQLLite-tests. Results are here http://global.phoronix-
test-suite.com/index.php?k=profile&u=jarkko-20379-5630-13562

Later I noticed that I's using xfs filesystem, so the results are not
comparable. But with deadline scheduler and nobarrier the results are
similar to ext3.

What's more worrying is that with cfq scheduler and barrier the SQLLite
results are extremly bad. cfq/barrier = 1603.34 seconds vs.
deadline/nobarrier = ~155 seconds.

Kernel version didn't seem to matter, 2.6.29-020629-generic with
deadline/nobarrier was about the same as 2.6.28-11-generic with
deadline/nobarrier.
