Definitely look at some form of cacheing.

A cheap first step might be to go with a couple of decent 7200 rpm, ATA100 (or whatever the hell they're calling themsevles this week) disks and RAID0 them. Striping Good. Also, make sure your IDE is spiffed up to the max. Do an: hdparm /dev/hda (or whatever). Make sure it's using DMA, unmasked IRQ, 32 bit i/o and, a multcount of 16. Benchmark your drive before and after, with: hdparm -t /dev/hda You should see >10MB per second after tuning up. However, I can't help thinking for your application There Must Be A Better Way. Do you really need to do substring matching all the time? Can you pre-build an intermediate results set that can be optimally queried?
