But I started a few tests (this machine is supposed to be a web server), and I've been very disappointed by the I/0 performances. In fact, the same query on the same database takes 2,56s on my old P4 (which supports about 300 persons on a vbulletin forum at the same time), and 4,80s on the new dell. Of course, the mysql configuration is the same, and I've launched the query a few time to avoid differences due to mysql cache. http://www.ambrisko.com/doug/ata Should help you. Doug A.
