How much work do you think it will take to get the Windows build to support having multiple worker processes? Is anyone already working on this? I volunteer to help later this month if I get a little guidance on what is required.

You can run multiple nginx sessions by seperating the config between them, the main http section will have to use a ‘uniqe’ port for each session, from there on you can seperate out the hosted websites and also assign each session its own cpu. You are however limited to a 65.000 connection max for all sessions. Another, easier, way for multiple sessions is to use 1 session as proxy to many secondairy sessions which will make routing the http port easier, this way also scales better.

I think we might benefit more from solving the select problem, with 8 separate workers as mentioned before you’re still stuck to 1024\*8 which isn’t that much more, found an interesting discussion about select, why it’s used and why it should not be used on windows systems: [http://groups.google.com/group/alt.winsock.programming/browse\_thread/thread/a041475f7312f9c5](http://groups.google.com/group/alt.winsock.programming/browse_thread/thread/a041475f7312f9c5) If select was rewritten you could run 4 worker\_processes with 10.000 worker\_connections each on their own cpu. Windows can handle this just as easy as Linux folks.

Do you know how hard it would be to do that with nginx? I’m a C/C++ programmer, I just don’t want to dive into this project if there are going to be lots of other situations that aren’t thread-safe.

I never said it was going to be easy, just that porting for win32 requires some win32 work as there are substantial differences between linux and win32 (duh). They managed to get php win32 thread-safe after all. Setup nginx as a front-end, make a pool with nginx back-ends (just like you would do for fpm with sockets or tcp) and from there on the back-end nginx servers are load-balanced from the pool front-end just like fpm would work, nothing magic about it.

Well this is all for one site where I want multiple workers to speed up response time if any particular request is slow. Can you explain how I could forward from one nginx to say 4 other ones, and then those could talk to my WSGI application? Thanks.

itpp2012, I’ll take a look at having a load balancing nginx pass to other nginx instances. I would still prefer to add some completion ports or something similar to nginx, but that will obviously take a lot longer than just running the chained-nginx scenario. Thanks.
