To have better performance with Psyco you need low-level style code, generally not lazy, etc, and adopt some programming conventions, so you may have to rewrite your routines for max speed. If some of your routines are too much slow there are many ways in Python to write faster modules, like Cython, Weave, Inline, Swig, SIP, ShedSkin, etc. For bioinformatics purposes I have found that Pyd + D language is good for me (I have tried Pyrex too few times, but I have lost my patience trying to track down in a jungle of ugly auto- generated C code where some reference count updates happen. Writing D code is hugely faster/better for me. Even writing a C extension for Python from scratch may be better for me because there aren't hidden things happening everywhere. I presume other people don't share this problems of mine because there are lot of people using Cython now). Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
