You can have multiple project windows open in IntelliJ, and opening a project from an already-running instance takes only a few seconds, so I don’t think that’s really relevant.
I wonder if ZGC in Java 15, now that it is GA, would clean up any lag folks see.

I tried both ZGC and Shenandoah (with plenty of heap space available) and haven't noticed much difference compared to the default CMS. Also, Shenandoah (or maybe both?) does not support compressed pointers, so there was a noticeable increase in memory usage.
But my startup monorepo I keep loaded in IntelliJ for days at a time and have never looked back. For the 1% of time it’s laggy due to a JVM GC or background indexing, the other 99% of the time it’s immensely productive to have e.g. full-stack debug breakpoints that Just Work, well-designed customizable gutters, integrated linting, and more.
