I have been maintaining a mod-perl/MySQL4 web search engine with about 3M records,
which gains and drops about 100k records daily.
It runs on a dual-Opteron 242 system with 8GB RAM, 15k SCSI driv, SUSE Professional

After some research, I chose a dual Opteron MySQL server for my new search box. For
storage, I only update the tables once a day, so I plan on putting my data directory
on a Linux ramdrive and backing it up to the hard disk after each update for maximum
performance.

I just built a P4 3.06 1GB DDR 333 15k U160 SCSI MySQL Linux server.

Every day I insert 76k records all at once and delete about another 76k.
While these inserts are happening, the select
