What kind of hard disk drive are you using? ATA/IDE or SCSI?
If ATA/IDE: is DMA enabled for the drive? hdparm -v /dev/hda

How much of the CPU time is spent in "system" and how much in "user"
space?  top(1) may not tell this, but time(1) will.

Which bogofilter version are you running, how have you installed it, and
if you compiled yourself, what were the compiler options?

Which Berkeley DB version are you using?

bogofilter -V will tell both pieces of information.
