250MB swapped, for less than 1 GB RAM, used is disastrous for an MTA.
Increase RAM to 2GB, or until swap is always "0k used"
It's just a single user home system. True, I probably do need to
increase ram but I 'don't' think this has a bearing on this issue though
I may be wrong.
Your system is swapping. That kills performance, pretty much across the
board. Either buy more memory or accept the impact of an underprovisioned
machine on the performance of mail delivery.
Do you really need your mail to be delivered _that_ promptly? If
interactive performance is acceptable then what does it matter if an email
(delivered in the background) takes 30 seconds or 300 seconds to be
stuffed into your inbox?
How many email users is this supporting? You might want to consider some
glue-level performance hacks - for example, if your box is supporting
email for your family members, and all delivery for that is local, then
you could configure your MTA to not pass locally-originated-and-destined
messages through clamav or SA at all.
