Don't use 5.0 for production. If you are going to put anything in
production, use a _very_ recent -CURRENT. Even then, 5.0 isn't as
fast as the -STABLE series at the moment because it's still in an
awkward transition between locking via giant and fine grain locking.
If you'd like to help figure out performance problems for -CURRENT
however, have you tried running any kernel profiling to see where the
kernel is spending it's cycles? -sc
