My server is running a heavy website and recieves mail for some 30 users

the load average to drag at times from a calm 1 or 2 up to 12 and even
20. this is actually hurting the websites' responsiveness a lot. I'm
afraid it's time to consider taking off rules from the list and risk
getting more false negatives through, or kick it out in favor of a
slimmer, non-perl alternative, though I have no idea which way to go.
the 3 spamd processes seem to be constantly taking 5-14% of the CPU for
several hours each night.
ideas?
A few:
1. Are you scanning everything? I don't scan anything over 256K, and
amavis docs suggest 64K.
2. The more RAM the merrier (isn't it always....)
3. graylisting.
4. Do you check for recipients existence before scanning?
5. more daemons? I use 4 daemons for 20 users (but this is only a mail relay).
6. Scan for virii before scanning for spam.
