Hi Eugen, I have the debugger working, I was trying to connect the profiler :) Finally I managed to connect from VisualVM on Windows thanks to this answer: https://stackoverflow.com/questions/66222727/how-to-connect-to-jmx-server-running-inside-wsl2/71881475#71881475
I've launched an infinite curl loop to create some query load, but what now? What should I be looking for in VisualVM?
