With streaming == True and cProfile added https://github.com/oberstet/scratchbox/blob/master/python/asyncio/tcp_echo_server_tx.py I get strange results. Sluggish performance: [oberstet@brummer1 ~]$ netperf -N -H 127.0.0.1 -t TCP_STREAM -l 10 -- -P 9000 TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 9000 AF_INET to 127.0.0.1 () port 9000 AF_INET : no control : histogram : interval : dirty data : demo Recv Send Send Socket Socket Message Elapsed Size Size Size Time Throughput bytes bytes bytes secs. 10^6bits/sec 0 32768 32768 10.03 0.31 === That is 310kb/s. Which is totally slow. The native C based netserver that comes with netperf does 46Gb/s on this test. With streaming == False, I get something like 11Gb/s with that Twisted server (until it collapsed due to OOM) The CPU load is very low (near 0%). The memory stays flat.
