We came the same conclusion at work. One of my colleagues has a machine with HyperThreading and he noticed no real performance increase with the processing library altough on my machine (which is a dual Core 2 Duo) the performance boost was definitely there :-) The good side of this is hyperthreading with parallel processes is like using a mono-CPU machine so we don't have to take into account it like if it was an entirely different kind of architecture. -- Lawrence, oluyede.org - neropercaso.it "It is difficult to get a man to understand something when his salary depends on not understanding it" - Upton Sinclair -- http://mail.python.org/mailman/listinfo/python-list
