Hi William, Sleeping processes are the result of persisitant connections and should not slow down your server. As to why you server is "so slow" you will have to provide specific examples of what is slow. We reach speeds of 600 queries per second on slower hardware. Also please indicated languages used for examples and versions of FreeBSD, MySQL and PHP (if you use PHP).
Also there are many tunable parameters (http://www.mysql.com/doc/en/Server_parameters.html) I recommend Paul Dubois Book on MySQL http://www.amazon.com/exec/obidos/tg/detail/-/0735712123/qid=104696018 6/sr=1-4/ref=sr_1_4/103-5030472-7439844?v=glance&s=books Best of Luck, Ken ----- Original Message ----- From: "William Wang" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, March 05, 2003 10:11 PM Subject: very slow mysql server, help please > > Hi All: > I have three web server (DUAL 1.4 G MHZ, 1G RAM) connect to one mysql > database server (DUAL 2.2 G MHZ, 2 G RAM), SSL accelerator and a load > balancer.
