Which kernel version are you using?

Supposing you are using 2.2.x if it wasn't VM related it's probably the elevator starvation thing. Could you try again with 2.2.14aa10 (it includes elevator-starvation-6.gz):
ftp://ftp.*.kernel.org/pub/linux/kernel/people/andrea/kernels/v2.2/2.2.14aa10.gz
For reference the elevator-starvation-6.gz patch alone is here:
ftp://ftp.*.kernel.org/pub/linux/kernel/people/andrea/kernels/v2.2/2.2.14aa10/elevator-starvation-6.gz

To be sure about what's going on could you provide me a `vmstat 1` log of before/during/after the performance drop?
