It really has no issue as long as you have enough RAM and disabled swap. I recently got a fairly decent gaming laptop that I'm supposed to develop on and the 16 GB RAM is constantly full and it's swapping all the time, browser keeps suspending my background tabs, really pain in the ass.

You really do not want to disable swap on Linux. The operating system does not handle out of memory situations well at all if you do.

At any rate, I've got 32 GB of ram and I'm operating off an NVMe-drive, I really don't see what the problem is.

Possibly dumb question, have you adjusted the maximum memory heap size that the JVM can allocate for running IntelliJ?

You're right, I should've mentioned this only applies to Windows pagefile rather than swap.
