Any data to back up this claim? My experience in dealing with large numbers of files, huge data sets, is that Perl generally roars, while python lags. I converted a python code to Perl associated with some recent work, and got a good ~2.5x overall improvement. It varied a bit as a function of the input, but generally Perl is superior in performance. Some areas Python is better, but not many.
