[Live-devel] Performance degradiation in Windows

[Hyung Jin Jung]

We are encountered significant performance degradation when ports live555 to windows from Linux.
Even though Window server has more powerful H/W spec. then Linux.

Test scenario
1. Run live555MediaServer (not modified)
2. Connect client to server stream (H264, 720p, 2mbps, RTP over TCP)
3. Increase client until video broken, skip...
- See video in VLC player 
- Check VLC log something like "picture is too late to be displayed (missing 88 ms)..."

HW spec.
Linux: E3-1220v2 / DDR3 4GB / 1Gbps NIC
Windows: E3-1240v3 / DDR3 4GB/ 1Gbps NIC

Result
Linux: 100 clients
Windows: 50~60 clients

Info.
- DFD_SETSIZE=1024
- Mingw32 (Ubuntu 14.04 package)
- Iperf result was fine (~900Mbps)

Any idea to handle this?

Thanks,
Davy
