Well, cross-language benchmarking is always hard, but for purely testing the GC this is not too bad: https://benchmarksgame-team.pages.debian.net/benchmarksgame/...

See how ahead Java is of any other managed language (and it doesn’t really make sense to do this benchmark with non-GCd languages)? Though this is done with the G1 GC, not the low-latency one - this default GC is more throughput oriented with a max pause time target goal. Also note how Java does use multiple times more memory, as it “postpones running GC when it knows it still will have enough time to collect all of it without running out of the target goal” - this is also the reason why java is quite ahead on “energy efficiency” reports as well. And also, GCs work better with more heap space.

Very soon businesses would be asking for "dollar efficiency" also. I think going by effort on Java and their frameworks vendors to pack more instances of Java process/pods on a VM, it is already been asked by tech savvy customers.

So that old fact that on sever side programing customers only care for raw throughput and not on machine size because RAM/CPU/disk is cheap is not working well in cloud based deployments where now each of these matter.

To be honest, I really don’t get this microservice/cloud hype, stackoverflow (which let’s be honest will be bigger than that 34th startup) runs on a single (very beefy though) dedicated server machine.

I pay like 5 dollars a month for a VM with very low params, but even that will happily run anything. Especially that the DB likely can’t be shared the bus factor will remain 1.

I agree on that. And the bureaucracy evolved around "Microservice Architecture" of Kube pods, service mesh and so many other pieces required for it feel like something we are trying to do it well, what should not be done in first place.
