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.
