through no fault of nospamtoday a clients server crashed over the weekend and was down for nearly 40 hours

When it was recovered it started to download the waiting emails (nospamtoday is configured as a pop proxy for the email server)

One account had accumulated 6766 emails which took 11.5 hours to download in one smartpop session, which averages 1 every 6 seconds, other sessions average a similar rate

The server is a dual quad xeon with 3.5Gb of available ram during the download the processor was generally 99% idle and the memory usage has not been above 1.9Gb since the last restart

The configuration runs the following modules
Whitelist filter A-K
Whitelist Filter L-Z
Attachment Filter
DNSBL Filter

The timings in the log indicate that the SpamAssassin filter takes between 4 and 6 seconds per email and Mail Storage usually 1 second

What can I look at in the spamassassin configuration to improve performance please
