Does anyone have a good "cook book" on how to migrate to dovecot from the
xinetd version of qpopper?

In the testing repository there's a version of poprelayd that I believe
works with Dovecot.
I have recompiled qpopper and then finally migrated to Dovecot. I am still
seeing issues with the POP3 service getting overwhelmed. Both qpopper and
Dovecot timeout under heavy loads. The machine is an Intel 3.2Ghz, 2GB RAM,
SATA HDD. There are around 1000 users. I don't know what else to do other
than move some of the users to another box. If anyone has any suggestions
I'd be glad to hear them.
