Giampaolo Rodola' added the comment: In those protocols where client and server exchange a lot of commands and responses in a single session, such as FTP, modify() is going to be called many times. I don't have actual numbers but I remember that using epoll.modify() was one of those relatively small optimizations which all put together led to current pyftpdlib performances. For poll() and epoll() pollers I see no reason not to use the specialized modify().
That aside, what actually *does* make a big difference and it is very important is to "unregister" a fd for writing (EVENT_WRITE) when there's no more data to send, and that's something that should be done at a higher level (transport.write() and anywhere else some data is sent). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19842> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
