You say you want speed, but I'm betting stability is more important
than speed, as a machine that crashes several times a month but is
lightening fast is usually a bad choice for a db server.
I run Centos 5.3 with an older kernel. There's a bug in the areca
drivers after the 2.6.18-92.el5 kernel that redhat has no apparent
interest in fixing. But with that kernel, I have a machine that's
pretty fast and stable:
uname -a
Linux db1 2.6.18-92.el5 #1 SMP Tue Jun 10 18:51:06 EDT 2008 x86_64
x86_64 x86_64 GNU/Linux
uptime
13:44:38 up 416 days, 28 min, 6 users, load average: 28.94, 31.93, 32.50
It's twin was the one I tested the newer kernel on and had the hangs
with. It now runs the same older kernel as well.
