We currently have 128 lists, and the Top Ten largest lists are: 3406 Python-list 3316 Mailman-announce 2997 Tutor 2598 Mailman-Users 1492 Python-announce-list 1309 Python-Dev 874 python-win32 855 Pythonmac-SIG 694 Image-SIG 646 XML-SIG Going back to May 2005, the Top Ten lists with the most traffic are: 35787 python-list 21220 python-dev 18747 tutor 16636 python-checkins 13810 mailman-users 11241 python-bugs-list 10184 python-3000 7754 python-help 5790 patches 5400 pythonmac-sig The Top Ten fastest lists with the highest average delivery rates to the MTA are: total delivery List # msgs time (secs) Avg. rate -------------------- -------- ---------- ------------- Tutor 18629829 / 104001.403 = 179.131 msg/s Baypiggies 747203 / 4413.775 = 169.289 msg/s python-win32 1649983 / 9783.514 = 168.649 msg/s C++-sig 1317540 / 7915.801 = 166.444 msg/s Edu-sig 801584 / 5248.601 = 152.723 msg/s Python-announce-list 2002410 / 13363.320 = 149.844 msg/s PythonCE 245065 / 1638.371 = 149.578 msg/s Python-ideas 131066 / 883.584 = 148.335 msg/s Image-SIG 465971 / 3271.483 = 142.434 msg/s Distutils-SIG 610489 / 4330.037 = 140.989 msg/s Now, we are a bit of a special case, since we dump all our outgoing mail on the ISP that provides hosting services for the Python.org machines (XS4ALL.nl), but as far as the rest of the numbers are concerned, I think they're fairly representative. -- Brad Knowles <[EMAIL PROTECTED]> LinkedIn Profile: <http://tinyurl.com/y8kpxu> ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq01.027.htp
