Perhaps the FreeBSD isn't one of the main differences, but I had to wonder.
I did a test today and I can see that amavis is taking longer on Redhat to scan.

BSD # # tail -f /var/log/amavisd |perl -ne 'chomp; /amavis.*, (\d+
ms)$/ &&print "$1\n"'
4047 ms
5257 ms
493 ms
445 ms
435 ms
438 ms
4487 ms

RH # # tail -f /var/log/amavisd |perl -ne 'chomp; /amavis.*, (\d+
ms)$/ &&print "$1\n"'
5400 ms
1122 ms
10374 ms
4841 ms
1637 ms
2715 ms
1241 ms
10778 ms
4604 ms

Redhat has these additional spamassassin plugins enabled:

[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::Check from @INC
[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::HTTPSMismatch from @INC
[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::URIDetail from @INC
[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::Bayes from @INC
[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::BodyEval from @INC
[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::DNSEval from @INC
[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::HTMLEval from @INC
[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::HeaderEval from @INC
[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::MIMEEval from @INC
[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::RelayEval from @INC
[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::URIEval from @INC
[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::WLBLEval from @INC
[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::VBounce from @INC
[12429] dbg: plugin: loading Mail::SpamAssassin::Plugin::ImageInfo from @INC

That's part of what makes Spamassassin better as things develop, but
it is likely also the source of the extra processing time.
