I actually did a full testing of qpsmtpd-apache vs forkserver when I first started building this cluster and the apache version just had way to much overhead. Basically it couldn't handle the connections per second we were throwing it. I asked the list for some help at that time, as I was thinking my config could be off, but never really got any. I've got a test box going with 0.40 and the pre-fork server now and it seems much better.
