The Edge server is using a lot of CPU

[ilpyoung]

Hello,

Currently, I have one Origin server and two Edge servers.

One is for production (8-core AWS Linux), and the other is for development (4-core CentOS 7).

When streaming two streams to the Origin and watching from the Edge servers:
• The development server’s CPU usage exceeds 30%.
• The viewing resolution is 540p.
• On the 8-core server, watching two 540p streams results in about 1% CPU usage.

Even for the 8-core server, using 1% CPU for just two 540p streams seems relatively high.

I have attached the Server.xml file.
Are there any additional aspects I should check?

Both servers are running on Docker, and the version is 0.17.3.

If you run top -Hp <pid> with the PID of OvenMediaEngine, you can see how exactly the CPU is being used.

Yes.
The CPU usage on the development server is:
72.0 1.3 0:12.96 OutboundWorker
10.0 1.3 7:46.24 AW-WebRTC0
10.0 1.3 0:01.89 StreamWorker
8.0 1.3 0:02.00 StreamWorker

The CPU usage in production is:
4.0 1.8 5:44.44 OutboundWorker
2.0 1.8 5:57.22 AW-WebRTC0
0.0 1.8 0:16.15 OvenMediaEngine

The OutboundWorker process on the development server is using an unusually high amount of CPU.

OME uses CPU resources for LLHLS/WebRTC packaging, delivering data to viewers, transcoding, etc. I think you are thinking that 1% CPU is allocated for 2 viewers, but it is not. Most of the 1% is allocated for packaging, that is, CPU resources required per stream, and less CPU is used for viewers.

Understood.

Then, what should I check to find out why the OutboundWorker process on the development server is consuming a lot of CPU?
