I did think about it, but maybe incorrectly.

I figured the kernel would not be smart enough to give a strong 
preference to caching the files that are getting written to 
(/var/db/spamd) over those files that are getting read a lot 
(SpamAssassin and ClamAV).  I figured that's why he qualified his 
suggestion with spamd being the only running on the box.

Or are you saying that caching the reads would help with the I/O bottle 
neck just as effectively?  I would be surprised by that, especially 
since it's RAID1.
