Please don't use inetd / xinetd if you're looking for performance. Both
spawn a new process each time there is an incoming request, which is a
*huge* overhead.
You definitely have to run qpopper (or any other POP daemon) as a
standalone server.
Other tips include :
- recompiling qpopper with other options (no debugging, optimization)
- reading http://www.eudora.com/qpopper/faq.html#performance
and keep in mind that the number of mailboxes is not a significant
number to compare performance. I'd rather look at the number of
connections / minute.
