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. m
