I may have observed this regarding performance. (RR + Pycharm) Perhaps the classic software move of: "[My] computers have gotten faster, but JB IDEs are still slow/unresponsive, so they are probably getting slower / more resource intensive".

They will bring a 9950x with nothing else running to a crawl. Then complain they are out of memory. (When it is obviously the IDEs themselves running the system out of memory)

I <3 JB IDEs for their functionality, but resource pigs they are.
