Check the timing report (at log level 2) to see what task was taking
most of the resources.

A message transfer from MTA to amavisd can take about ten seconds
for a 100 MB message on a reasonably fast machine, the rest depends
much on a contents type - decoding and virus checking. You won't know
what was it until you look at the timing report. A transfer of a message
from amavisd back to MTA is about an order of magnitude faster than
receiving it (unless you have a very old version of amavisd),
so should not be a problem. For a message of this size, spam scanning
was skipped ($sa_mail_body_size_limit).
