Ah. In that case, if you've got enough (your definition, not mine!) RAM then you could put the SpamAssassin working/Bayes directories onto a RAM disk. In fact, while you're at it, put your Exim spool databases onto a RAM disk too. You'll marvel (hopefully) at the boost you get in performance. Implementation is left as an exercise for the reader, particularly with respects volatility of data and (where necessary) keeping hold of it across service restarts and/or system reboots.
