Mmmh, your system version might have been compiled with different options, so you may want to compare with a hand-compiled gcc build. The "text" column gives you the code size. Arguably, a smaller code size will make the instruction cache more efficient. cheers Antoine. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
