Re: [SR-Users] EVAPI workload allocation across processes

Hi Alex, not the author of this module - but I think you are right after having briefly looked to the code. The dispatcher process accept(..) the connections and then pass them to the worker processes for further processing.

My best guess is that the EvAPI dispatcher process is the sole accept()or of client connections and the place where all relaying to client connections is done, regardless of their number, and that the ‘workers’ represent an async pool of processes in which TM transactions can be resumed or other work can be done when an outside caller sends a message to the dispatcher. However, the documentation[1] is a little vague on the meaning of the ‘workers’ modparam: "Number of worker processes to be started to handle incoming messages from remote applications.” Or maybe it’s not. Just wanted to confirm that my understanding is correct.
