Clion 2022.3.2 is extremely slow. Follow
It becomes unresponsive after 3-5 min of use.
I use Power Save Mode to improve performance it helps but not for long.
in Activity monitor most often:
- <JIT compiler>
- <infrastructure: AWT-AppKit>
- <unidentified: UI thread>
It's consuming all my CPU even when there's not background tasks?
Is there a way to limit CPU usage?
If there's no could you prioritize this feature? Just make some internal jobs single threaded.
Mean time I have to switch to VSCode :(

Andrey please capture a CPU snapshot while reproducing the issue and send it to clion-support at jetbrains.com so that we can take a look.
Sbachmann the same request to you.
In there article you suggested, it says: "should click on Help | Diagnostic | Start CPU Usage Profiling."
I don't have it.
Here's what I have:
I also noticed it reindexes Google tests, python venv, and other files before/after each debug run, even thought there's been no changes whatsoever.
May be you'll just add some simple timestamp checks and add sleeps in loops to yield cpu as a quick fix. otherwise CLion completely is unusable.
I realized that CPU snapshot was in a plugin. I disabled all plugins trying to alleviate the problem.
I'll record the snapshot.
