http://www.oreillynet.com/pub/a/linux/2000/11/17/low_latency.html This is an article from O'reilly explaining how to supercharge your linux box. It talks about hdparm and a couple of other things, and then has a lengthy description about how to patch your kernel to optimize certain parts to reduce latency inherent in the linux kernel. It's too cool. -- Michael J. Smith [EMAIL PROTECTED] 2250 Patterson #25 Eugene, OR 97405 (541)346-7562
