So he is right, and Linux did have a problem on this
workload. Basically it was a combination of a glibc
inefficiency and the fact that nobody seems to have
reported such a workload before. The fix was basically
a small change to the way malloc/free works, and a
little patch to the kernel to optimise the new path
used by glibc.
That post found the fixes to have eliminated the big
dropoff. Note it still doesn't scale past 8-way, but
this is likely to be a MySQL issue -- BSD doesn't do
to post comments)
