Hi Daniel,Thanks for you reply, I have ported spdylay to libcurl and enabled multiplexing.But the test results of spdy performance is not good here.The persistent connection is not reliable, sometimes it will be dead.Especially when client process is killed, while server wasn't informed, then the next new connection could face connection timeout, which costs lots of time.
