when to use Linux SMP kernel?
We loaded Redhat ES 4 and on bootup, it defaults to the SMP version of the kernel.
With one processor (though it is dual-core), should we be using the SMP or non-SMP kernel?
How would we know this ourselves - is there a good document explaining this anywhere?
What advantage (if any) would the SMP kernel give us, or would it depend on what applications we were running?

Re: when to use Linux SMP kernel?
SMP means symmetric multiprocessing, as in 'multiple cpus are doing Your work'. A dual core cpu is essentially two cpus in the packaging of one, so You need to run an smp kernel.

Re: when to use Linux SMP kernel?
If it's modern (i.e. last 5-6 years or so), then you turn it on, and never think about it again.
With RHEL4 and a G5 series server, turn it on and leave it on.
