Hi, 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 performance? Thanks for a brief answer Carsten
