Could it be that the Performance Testing plugin https://plugins.jetbrains.com/plugin/7819-performance-testing does not work with the free of charge IntelliJ IDEA community Edition?
I was able to install the plugin, but the option 'Enable CPU Profiler' is not showing under Help/Diagnostic Tools. There is an option 'Start CPU Usage Profiling' however. Is that the same and the documentation is just not up to date?
At the end I just want to do some memory utilization analysis and I thought that the performance testing plugin is what I need. Can I do some memory analysis out of the box with IntelliJ otherwise?
