Usually a mirror subrequest does not affect the main request. However there are two issues with mirroring: - the next request on the same connection will not be processed until all mirror subrequests finish. Try disabling keepalive and see if it helps. - if you use sendfile and tcp_nopush, it's possible that the response is not pushed properly because of a mirror subrequest, which may result in a delay. Turn off sendfile and see if it helps. -- Roman Arutyunyan _______________________________________________ nginx mailing list [email protected] http://mailman.nginx.org/mailman/listinfo/nginx
