I created a Thunderbird folder of 26 Google alerts and just parsed then all after reading them in from the mailbox.
2.5 (!): 0.78 sec 3.1 : 42.80 sec Rather than debate the code here perhaps I should just open an issue for this? I can then provide both a program and some data, which can be added to the tests if appropriate. The issue can clearly stand some investigation. regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 See Python Video! http://python.mirocommunity.org/ Holden Web LLC http://www.holdenweb.com/ UPCOMING EVENTS: http://holdenweb.eventbrite.com/ "All I want for my birthday is another birthday" - Ian Dury, 1942-2000 _______________________________________________ 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
