uWSGI creates a pool of processes with a number of threads in each and then they are used for the whole server life cycle.

It is cool because it simplify deployments, but nginx is not an application server, so things like multi-strategy gracefully reloads, stuck-requests managers, offloading and so on are not available. Regarding the "ipc problem", you generally put a load balancer on front of your app, so there is always ipc Do not get me wrong, as i have already said your project is cool, but you should focus not on performance but on better integration with the nginx api for writing non-blocking apps (if possible), something at uWSGI unfortunately failed (the JVM has no support for switching stacks out of the box, something that is required for async mode in uWSGI) -- Roberto De Ioris http://unbit.it -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
