Little bit offtopic; I try jetbrains ide's every time I get a new laptop; lately Rider for a 1m+ LoC c# project on my 16gb m1. It is unusable. I like the features but it is so incredibly slow... and it gets even slower as the day goes on.

(I am very keen to tell people who are in the same despair as I was about how slow JetBrains apps are out of the box -- hope it's not considered bad form to link to one's own blog post about it.)
Rider 2021.3 has an M1 build, and makes a big difference. It's currently in preview (https://www.jetbrains.com/rider/nextversion/) but will be released in the next week or so.
I wonder if JetBrains has some incentive to keep Mac users happy at the expense of others, because there is no justification for the unacceptably bad performance of CLion, PyCharm, and IDEA with a version 11 JDK on Linux, given how much better it is on JDK 15/16.
I have never seen any indication that they have are going to address this, nor have they even acknowledged that it's a problem, nor that they intend to upgrade from JDK 11 to something more up-to-date. Still, they have 1 year and 10 months from now until the end of active support, so perhaps this might provoke them into action.
The fact that JBR even exists is a red flag. Should every vendor ship their own JVM?!

tells that JetBrains have been working on a JDK17 version of JBR for 2022.1, which amazingly, is almost upon us. I am looking forward to seeing what it's like!
Try the Rider EAP with .net 6 - I find native arm64 .net flies on my M1 mac mini and M1 Max 14" MBP.
By the way, sometimes a corrupted cache can be a problem. You can fix this via File -> Invalidate Caches.

CLion is very fast on either. I guess gobbles of RAM counts. I also have laptops with 32GB RAM each but did not try it on those as I no longer use laptops for development (no business need).
Still as my main development language for backend is C++ I mostly use Visual Studio. Especially since their preview version allows seamless development / debugging on remote Linux server. Hard to describe but it just fits me better, feels more "natural".
