Regions of RAM will operate more or less quickly depending on which core accesses them. AMD chips tend to be NUMA by design. If that has changed I'm all ears, but you don't need a special motherboard to have a NUMA AMD64 system. You basically don't get a choice in it. If the kernel doesn't take that into account, then software will run slightly slower since it might run on cores that aren't optimized for the region of memory their data is stored in. -- Rich ___________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.phillylinux.org/mailman/listinfo/plug-announce General Discussion -- http://lists.phillylinux.org/mailman/listinfo/plug
