+1 for async-profiler! It can let you get a much bigger picture than
is possible with most other profilers, and it often shows you
immediately what's wrong. For example:
JDK 13 Performance
https://jgneff.github.io/framebufferY8/2020-05/#jdk-13-performance
It would be a nice addition to the NetBeans profiler. :-)
there is an issue for that (for flame graphs specifically)
https://github.com/apache/netbeans/issues/3849
I suppose it would be nice to have an async-profiler plugin for
discoverabiity reasons, but I personally would keep using it's CLI since
it doesn't require any setup anyway.
