I'm of this school of thought: if you're doing anything with moderate to high traffic, you should be running NGINX on port 80 , with a proxypass to something else.
What you proxypass to, however, is up to you. 1- paster 2- wsgi 3- apache the important thing is to get Apache off of port 80 , its really just not a great performer. you *especially* don't want to run apache on port 80 if you're using a single apache configuration. the mod_perl folks did the math and wrote a chapter or two about it, which may have wound up online... it was called "vanilla apache + mod perl" or something like that. you basically want the lightest and leanest server running on port 80 as possible (nginx, or a stripped down apache with as few DSOs loaded as possible) . you can then proxy back to other servers as needed. if you decided to stay apache, you DEFINITELY want to run a vanilla instance on port80 to handle static files and proxy back. the reasons for this are twofold: 1- IIRC, a stripped down apache process is 500k or so of memory; a mod_* will grow to 3-5MB, and then compile in your application code and allocated/reserved memory... which often ends up at 20-30MB per process. if you run your app on port 80, both static files and dynamic content will be served by these apache processes - which means you'll tie up the 20-30mb processes with tasks a 500k one could do. if you profile your app correctly, you can find the right types of servers to run that will easily allow you to increase your throughput by 10-20x -- if not more -- just by smarter resource allocation. 2- if a client is slow, or drops a connection without being detected, your dynamic apache ( or anything else ) just sits there sloooowly serving a file until a timeout is reached. if you put a 'vanilla' server on port 80, the dynamic server instantly returns the result to it... and it can handle the timeout/slowdown issues... freeing up the memory and processor for the dynamic server to process another request. -- You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
