It is not the IDE per se (300 MB RSS or so), but Java allocating some 2 GB heap per process, which also includes gradle daemon and compilers.

This can easily eat a bunch of ram, making the OS swap. Seems OS X has extra bad policy of swapping.

I gave Android Studio 8GB of heap space to play with, and it still manages to run out. WTF.
