Hi, I am running quite big application using Pylons and now I am in the moment on performance tuning etc. I have some questions about your experiences and best practices.
My first configuration is something like that: I have one machine with e.g. 4 paster instances and haproxy in front wchich works as load balancer before those Paster backends. Haproxy have a nice feature, where I can set maxconnections to backends parameter. Since Paster is multi-threaded server I can set this parameter to value graeater than 1 (this parameter set to 1 is especailly useful with Mongrel/Thin in Rails since it is single threaded server). When this value is set, haproxy does not sends requests to particular backend if it see that backend is handling 'maxconnections' requests and tries with another backend (so It is more sofisticated balancing than simple round-robin). And my question is: how many should one instance of Paster handle requests simultanously? Is it better to run more paster instances on single machine (for example allowing only one request go to one paster in particular moment, you know - GIL problem or sth) or allowing 10 requests in one moment, or even 100 is not problem for single instance?? I noticed that Paster have default worker number set to value near 10. I am also considering CherryPy as backend server or maybe something else which you suggest? If there are better servers in your opinion than Paster, how this situation looks in there?
