Running my Verilog parser tests, I get a 5-10% slowdown with Python 2.5 vs. Python 2.4.1 (See http://pyparsing.wikispaces.com/News.)
I apologize for not running performance tests sooner, I only ran regression tests on the release candidates, and those were all okay. I'll look through the "What's New in 2.5" and see if there are some features I can take advantage of for the upcoming 1.4.4 release (while retaining backward compat with Py2.3). -- Paul -- http://mail.python.org/mailman/listinfo/python-list
