It definitely was easier for the projects I worked on, but they are exactly the use case where the heap is long lived and most of the machine.

I’ve also worked on systems with lots of small processes, and the operational issues that creates dwarfs GC problems: It takes one middle tier machine, and adds 64-128 network boundaries, and also creates an extremely difficult static memory allocation problem.

I know people do it anyway, but it’s rare that they can articulate a decent technical reason for it, and it wastes something like 90% of the hardware (even in carefully optimized code bases / deployments).

Anyway, I’m not the target market for such stuff.
