You are not the first to report that BDC is a bit heavy on the CPU....
and if you run both as command-line tools (as if you have any choice
with BDC:-), and have a fair amount of incoming traffic, then the
fork/exec/read virus defs/etc overhead will begin to tell. If you
don't already, run clamavmodule instead of clamav... Will likely solve
it for clamav, at least.
