Transmission message rate on youtube #12

There was a message on YouTube about the transmission rate not being healthy enough. Should make sure it was not a local WiFi issue trying with a proven fast and stable connection.

Reading this post https://dzone.com/articles/rtmp-performance-testing-with-jmeter-learn-how We may be able to set up some tooling. With one of the plugins to measure. Also something to consider is a test with streaming a file already on the server, so elimtae the question of WiFi upload and narrow down if the problem is in uploading, processing, or streaming.

What kind of performance issues are you seeing?

There are a few things you can try:

1) At the encoder: check the stats dock in OBS if there's too much recording lag, encoding lag or dropped frames https://twitter.com/obsproject/status/1100167198876803077 2) At the server: use top to see realtime CPU/memory usage https://linux.die.net/man/1/top 3) At the server: use iftop to see realtime bandwidth usage http://www.ex-parrot.com/pdw/iftop/ 4) At YouTube: look for errors in the Live Control Room

Also make sure that you use a Google Cloud instance that's near you, as you will get more bandwidth that way.
