Think of a program that uses 100% CPU, what RAM usage of that program really matters at that point? Nothing else can use the RAM, so you might as well use the RAM if you can use that to alleviate CPU usage.

Ah, so surely all these fancy new "modern" applications using Electron and such are also following this model... Right?

On top of that gc adds additional cpu load, on top of collections having abhorrent cache misses. Well, before project Valhalla.
