Cores not threads :) Yes, they will be 2000 and two of them will be executed in parallel. The other area that is O(n) is the timeout management. What happen if you do not set timeout ? Regarding dynamic allocation, i want to be sure that no part of the async stack is O(n) after that we can start thinking about other-kind optimizations -- Roberto De Ioris http://unbit.it _______________________________________________ uWSGI mailing list [email protected] http://lists.unbit.it/cgi-bin/mailman/listinfo/uwsgi
