This looks buggy assumption to me. We use epoll() with in the order of millions of fds per epoller, and typically one napi_id per cpu. With your model, we would have to use nr_cpu epollers and make sure that sockets are properly placed on those epollers by their napi_ids. ------------------------------------------------------------------------------ Introducing Performance Central, a new site from SourceForge and AppDynamics.
