When the reader does not expect to read lots of data, it can set BF_READ_DONTWAIT on the request buffer. When it is set, the stream_sock_read callback will not try to perform multiple reads, it will return after only one, and clear the flag. That way, we can immediately return when waiting for an HTTP request without trying to read again. On pure request/responses schemes such as monitor-uri or redirects, this has completely eliminated the EAGAIN occurrences and the epoll_ctl() calls, resulting in a performance increase of about 10%. Similar effects should be observed once we support HTTP keep-alive since we'll immediately disable reads once we get a full request. |
