I can't address this specifically for FreeBSD as none of our FreeBSD systems are running at high load levels, but I don't think that clamav is the limiting facter. We're processing around a half-million messages a day at an ISP through a single public MX server which runs postfix, amavisd, and clamav to prescreen incoming messages, forwarding them to a cluster of servers which do the mail delivery to NFS mounted Maildir stores after doing spamassassin scoring. The load average on the border MX server rarely gets as high as 1.00. Frankly I've been amazed that it handles this volume that easily. The border machine is running a Pentium(R) 4 CPU 3.20GHz with 2GB of RAM which isn't a high performance machine by today's standards. The OS is SuSE Linux Enterprise 9 SP2. We don't have any FreeBSD machines running this configuration with significant loads for comparison.
