Indeed memory usage is much lower with this setup, but I had a lot of strange errors that were possibly related to thread safety. For example template loader stated that template doesn't exist, but in fact template was there. I've found a ticket for this, with a patch, but after applying it I've received other errors, that I was not able realize why they happen and I was not able to find any possible thread safety problems within error related code, eg.: (...) File "/xyz/django/template/__init__.py", line 785, in render output = force_unicode(self.filter_expression.resolve(context)) File "/xyz/django/template/__init__.py", line 518, in resolve obj = self.var.resolve(context) AttributeError: 'FilterExpression' object has no attribute 'var' I'm not 100% sure that these errors are because of multithreading, but I suppose they are. As my apache stopped working twice in the last 2 days I've decided to switch back to prefork immediately without further investigation. > Whether you use Apache worker MPM or not, when using mod_wsgi you can > also use it in daemon mode.

Thanks for all the links, I've already set up one application using wsgi in deamon mode at Webfaction :) It works, setup was easy, memory usage seems to be lower, but it is only one application so far. Now I have to setup virtual hosts and other applications with wsgi and see how it works altogether and in which configuration. -- Maciej Wisniowski --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
