What were your configure settings?
I configured qpopper with the temp-drop-dir=<some other partition>
deliberately and noticed that the performance markedly improved (as I
thought it would - since moving it should reduce disk seeks...)
Our configure settings were extremely simple (compared to some I have
seen on this list):
configure -enable-servermode -enable-temp-drop-dir=/var/pop
