Hi,

I'm interested in such a workload test. At my job we run various other
servers which have a classic virus/antispam environment. And unfortunatly
clamd behaves not very well on FreeBSD (see mails to freebsd-threads),
and this happens even on 2-CPU systems.

I think its not very difficult to make a scripted load test, with 2/4/6/8/16/32
scans in parallel, with ULE or BSD scheduler.

Btw: what is the best method to profile a threaded application to see where it
spends the most CPU time ?
