Just in case you haven't tried that yet, increase the IDE's memory heap size. That solved the problem of sluggishness for me.

Why hasn't Java added an option for automatic heap sizing for the desktop application use case (or any use case, for that matter)? Seems like a no-brainer thing to add, so I guess there are Reasons(tm).

It has. Modern JVMs can use as much memory as they "need" to, but for some reason JetBrains don't use this feature. I think after they upgrade to Java 17 they'll get it. But this has really killed their brand for a long time. 99% of the time people complain about their IDEs being slow it's because the app is GC thrashing and burning CPU rather than increase heap size.

I was under the impression that every gc still defaulted -Xmx to 25% of available memory.

It is configured by jetbrains (I guess to not use as much memory as Java would default to)
