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.
