Writing everything in C might be possible - but is a daunting task & not justified by the results. And wherever the standard libraries make use of the flexibility of Python, it's questionable if there really was any performance gain at all. But what REALLY is questionable is the alleged performance advantage - how do you back that up? According to the well-known (and surely limited) computer language shootout http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=all Python is roughly 25% faster than PHP. Granted, this is just one benchmark, with questionable real-life relevance. But where do you get the impression from that PHP is faster than Python then? diez -- http://mail.python.org/mailman/listinfo/python-list
