The systems are dual processor Dell 2450 w/ perc raid running Red Hat 7.3 - Following the best practices from the sendmail BOF at Linux World, we've installed sendmail 8.12.5, and have created 16 queues on reiserfs partitions which are mounted -notail, -noatime. Do any sendmail/kernel gurus have words of wisdom on recommended kernel sysctl params for such a beast? I mean they look good, but I'd like to make sure I'm getting the best possible sendmail performance and not missing anything. The sendmail guy at the BOF lost his laptop or something and didn't have the recommended params handy - I haven't been able to raise him since then either. Any pointers, or whacks with clue-by-fours are gladly accepted. Best Regards, Joe
