Performance issues


we are experiencing performance issues on our acceptance environment (BR Cloud). I was wondering if there is a way I can monitor the server performance concerning cpu & memory usage.
Also, I checked the logs and although I’m not an expert on this subject, it looks like garbage collection is frequent and not so quick: on average 0.15 seconds per collection . Sometimes collection intervals are 0.8s, sometimes 10s, which might explain the “sometimes it is fast, sometimes it is slow” feeling we have.

Anyone has tips how to investigate to be more sure what the cause is?
