Hi there.  I'm running clamd, invoked via mimefang by way of a sendmail
milter on a FreeBSD 5.x system.  Normal operations work perfectly, but I
run into these situations where I get a massive influx of mail (5k
messages in short order) and run into problems with clamd.

The short story is that mimedefang throws an error saying there's a
problem running the virus scanner, and mail tempfails.  Load on the box
skyrockets (normally around 4, goes to 40+)

If I comment out the clamd call in mimedefang, load drops and mail flows.
I'm looking for performance tuning pointers for clamd.  I'm already
planning to move to a tmpfs based Mimedefang directory in the hopes that
that will help, but would be interested in any other ideas.

I've searched the archives and looked at the FAQ and didn't seem to find
anything that specifically addressed performance parameters, but would
cheerfully accept pointers if I missed something.

Thanks

Ben
