Performance Linux/Windows

[ilcalmo]

I am using go2rtc standalone to restream 9 cams with 2 clients: frigate and Essential+ by Milestone. I installed Debian bookworm on a Onlogic CL250 and used the go2rtc binary for amd64 (stable and nightly build) and the CPU usage of the go2rtc process was about 38%-45% Same CPU usage (only go2rtc process) on a Debian bookwork in a system based on i5-7300U with the same config file, and same CPU usage also with Docker. On the Onlogic CL250 I tried Win11 IOT and installed the go2rtc binary and the same related config file of the other systems. The CPU usage of the go2rtc process was always between 15-20%.!!!

All the tests have been done only with go2rtc running. No other process such as Frigate or other stuff.

Since I am a Linux supporter and looking always a Linux alternative for everything, I am wondering how this can be possible!

Any comments/suggestions? Am I wrong somewhere? Thank you.

There's too low information. Start by providing information for all streams - /api/streams. You can remove all sensitive data.

Here is the config:

api:
  listen: ":1985"

rtsp:
  listen: ":8554"

streams:
    Cam0:

Stream info is a URL from go2rtc WebUI. If you remove stream name from this URL - your will get info for all streams

Ok fine, I got it! I attached a text file to avoid a very long msg (more than 1000 lines).

Some sensitive data are replaced with "user:pwd", some cameras url are dynamically generated, so passwords change on each connection. Cam0 is used only from a client. Cam8 is not used, even if configured, since it allows multiple connections, and I let each client to connect directly, to avoid more load to go2rtc.

Thank you.
