-m is design to use all of the CPU, so that the scan finishes sooner.

I wonder what would happen if you nice'd the clamd daemon
so that other processes had priority. That would make the
scan lazy. Don't use -m with this, and don't try it on
a machine with users or OnAcc: it might work, but it
might lock the machine up.
