Why am I able to understand that quite well? :)

While SpamAssassin is known to be a beast when it comes to mail
processing time and used memory, especially when running spamassassin
directly rather to use spamc/spamd, it would be helpful to know real
values. So, what do you call "extremely"? About how much mail per second
/ minute are we speaking? And last but not least: how powerful is the
machine the MTA with the helper applications is running on? Another
factor is the average size of mails to be processed.

Side note: I am running Sendmail with MimeDefang (Perl application using
embedded Perl code), which binds SpamAssassin to the mail processing
stream, and it has no real problem to handle my daily mails (600?; most
list mails). Anti virus protection is coming with ClamAV being the
primary milter to discard virus / worm mails without further processing
by other parts of the mail system.
