I really doubt if all your django sites will be slashdotted at the same time. Anyway, if it happens it is already DOS or DDOS attack. I'd better leave maxchildren=90 for each site and think about getting more power for servers if the average load grows in long run. > Well, might not be a problem you have with django/python and I might > be looking at the wrong thing, but at least in php, I found it that > putting a maxchildren low enough so you drop new requests before > overloading the server avoid problems, and having one fastcgi server > for all the sites works better than independent ones. What is your > experience with django (mod_python shared pool of processes vs. > fastcgi separated ones) ? I have no experience with mod_python as I have been using django only with lighttpd and apache with mod_fastcgi. I like the comfort that I get by running processes where and how I want. I am sure that there is plenty of peole on list (including core team) who use mod_python and could be more useful than me.
