yes - without real load...it all depends on tuning the box/environment. 
amavisd/clamd/vexira (our second av scanner)/dspam dont get much mails 
delivered because of our extremely strict postfix anti spam config 
(mostily at the smtp level - BEFORE fully accepting the mail)...we block 
around 90-95% of junk at the doors and let the other (resource 
intensive) daemons/services do the final cleaning. also keep in mind 
that we are talking about an inbound antispam/virus gateway - no 
pop3/imap or stuff like that...drawback is: we cant integrate things 
like full av/spam quarantine into this system - but on the other hand we 
have an extremely low false positive rate (when it comes to 
RBL`s/DUL`s/RHSBL`s etc. im real "picky") - and greylisting also helps 
much (we use gld / http://www.gasmi.net/gld.html).
