I have not compared them directly to be able to answer. I do know that the more cores the better (even slower ones) because each core divides the entire workload of the scheduler and increases the total threads that can work in parallel.
also you can start FS with -hp (high performance) which activates the round-robin scheduler, increases some ulimits and forces all consumed memory to be permanently resident with mlockall (no swapping) On Fri, Jan 30, 2009 at 11:05 AM, [email protected] < [email protected]> wrote: > Given the choice between dual core and dual processor, would one work > better than the other for FS?
