I'm a fanboy of both JetBrains and VSC. In the many years I've used JetBrains IDE variants (IntelliJ, Webstorm & Pycharm), I was never able to get rid of the frequent project re-indexing that slows everything down and makes the fans go crazy; you'd think they would cache that info and write it to disk.

They introduced recently an interesting feature: https://blog.jetbrains.com/idea/2020/07/shared-indexes-plugi... that might help with indexing of some shared libraries. I have not experience with this feature, but it looks promising.

Frequent re-indexing sucks and and times it slows you down. But I see it as a direct price to pay for intelligent autocomplete, search, refactoring, etc.

It also eats a lot of memory :(

It is cached and written to disk. Actually they're now going further and supporting downloads of pre-calculated indexes.

I use IntelliJ every day and I'd say reindexing only happens now when there's an actual need for it, like because I switched to a different JDK (which may therefore have different classes in the std lib). It's incremental too so this doesn't bother me like it used to. Definitely an area of focus for them.
