[Red5devs] Question Regarding Load Testing RTMP

[mabrek]

RTMPClient from trunk is usefull for load testing. Make a search through
users maillist for Red5Bench  and FLVRecorder
http://www.nabble.com/RedBench-to16173475.html , it can be used as a base
for your load testing application.
Beware, RTMPClient consumes more resources per user than server. Don't
forget to increase ulimit -n (number of open files) if you are on linux and
decrease -Xss (jvm stack size) to run many threads.
>From my results I can conclude that one server instance can handle about 3k
concurrent users watching live stream and delay between streams sent and
received can be up to 20 seconds (more users - longer delay). Profiling
showed that PlayEngine.pullAndPush synchronized method causes it, lock is
aquired too often an too many threads waits on it.
