Well it could schedule processes on processors in ways that force less than optimal memory usage patterns. But maybe you should tell the Altix folk with their 32-processor 384Gb NUMA machines what you've "been told" about Linux not being that good in NUMA. Really, these kind of cargo cult anecdotes are pretty pointless. -- greg ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
