given that many core Xeons (especially quad and/or many socket systems)
have some memory speed issues. With NUMA the kernel seems to be able to
optimize this somehow. However, I have two questions:
(1) Which EM64T Xeon supports NUMA? I've searched a bit, but I have not
found a definitive answer so far. Is this visible from /proc/cpuinfo?
(2) More importantly, has someone measured (how?) if this improves
Thanks for a brief answer
