Use top(1) to to view processes.

With Red Hat, using the sadc (system activity data collector) with sa and
sar can easily tell you wwhat processes/programs are your resource hogs.

(Your BSD/OS had similar with lastcomm and sa.)

Debian is great. NetBSD is also great and very similar to BSD/OS (as
another alternative).

No performance issues using vm-pop3d, exim (MTA), apache and
OpenWebMail with around 10,000 email accounts on similar hardware.

In the past, when using qpopper with 10-15,000 accounts, I improved
performance by using qpopper "server" mode.

Good luck,
