[Performances test WebRTC] Deplay or packet loss is too high

[hugmahit]

Describe the bug

• Performances test with Webrtc by OvenRtc Tester
• Edge high CPU, this CPU usage is normal?
• deplay or packet loss is too high

To Reproduce
Steps to reproduce the behavior:

1. Set Edge as follows Edge.xml
2. Set Origin as follows Origin.xml
3. With Encoder OBS
   
4. Test ws://domain:8333/app/stream by OvenPlayer demo

Server (please complete the following information):

• OS: 20.04.1 LTS (GNU/Linux 5.4.0-42-generic) - 48 cores
• OvenMediaEngine Version: #610338b
• Branch: master

Additional context
top -H -p [pid]:

OvenRtcTester: Test with ws://domain:8333/app/stream ~ 500 players

If it is correct that 500 sessions are connected, the cpu usage seems higher than my development environment. The most cpu consuming task in webrtc transmission is srtp encryption. what is your cpu?

The CPU of my development server is AMD Ryzen 9 5900X.
I set the video bitrate to 1Mbps just like you. StreamWorker is set to 16, but CPU usage is lower than your environment. It seems to be a clock speed difference, but I'll check later if it's an issue with the hardware encryption module.

Although unlikely, have you ever tuned a Linux network?

Thank you!
I will try tunning a Linux network. If there is any problem I will report back to you soon.
