On this benchmark 2.6.25 is the worst kernel yet:

I don't remember seeing a follow-up on this issue from last year.
Are there still any particular kernels to avoid based on this?
I never got any confirmation that the patches that came out of my
discussions with the kernel developers were ever merged. I'm in the
middle of a bunch of pgbench tests this week, and one of the things I
planned to try was seeing if the behavior has changed in 2.6.28 or 2.6.29.
I'm speaking about pgbench at the PostgreSQL East conference this weekend
and will have an update by then (along with a new toolchain for automating
large quantities of pgbench tests).
