I meant "numeric is slower than numpy", that is, modern numpy (0.9.8) appears to lose out majorly to numeric. This doesn't make much sense, so I figured there was something wrong with my benchmark, or my numpy install, and wanted to check if others had seen this sort of behavior. ...Eric

On a whim, we were [EJ]: benchmarking numpy vs numeric and have been lead to the conclusion that [EJ]: numpy is at least 50x slower; a 1000x1000 matmul takes 16 sec in numpy [EJ]: but 300 ms in numeric. You mean the other way around? I also tested numpy vs numarray, and numarray seems to be roughly 3 times faster than numpy for your particular testcase. J.
