[Live-devel] Performance degradiation in Windows

[Hyung Jin Jung]

As you presumed I just run single program and we use another tiny RTSP client to generate heavy load. (just stream, not decoding)

Regarding socket descriptor limitation,
I already increase it to 1024. Before do this, we stopped at 32 clients (32 * 2 sockets, RTP, RTCP)

some strange thing is
Why windows doesn't consume CPU resource compare than Linux.

Is it meaningful to compare calling interval  of MultiFramedRTPSink::sendNext()?

First, I presume that you’re not trying to run more than one copy of VLC on the same computer.  (VLC doesn’t scale well if you run multiple copies of it on the same computer.)

In my experience, problems like this are often caused by running into an (operating system-imposed) limit on the number of sockets that your application can have in use at any time.  See
