I had similar timeouts after upgrading to SA 2.60. I eventually
realised that they were due to a bayes autolearn triggering the expiry
process, which took up to three minutes when run separately (running
on a Pentium Pro 200, though my files are rather smaller than yours).
SA 2.61 claimed "dramatically reduced memory usage of Bayes expiry"
but it doesn't seem to have improved the speed much. 

My workaround has been to add a short script to my cron.daily to
ensure that it never has to do the expiry as part of an auto-learn.

| #!/bin/sh
| sa-learn --force-expire --rebuild
| chown postfix.postfix /var/spool/MailScanner/spamassassin/bayes*
