> Java performance isn't the fastest, that's ok, a close 3rd place behind C/CPP ain't bad. And you're still ahead of Go, and 10x or more ahead of Python and Ruby.
Fastest at what, exactly?
Fastest at what, exactly?
So giving the entire system to the JVM, performing some warmup prior to a service considering itself “healthy”, and the JVM was reasonably fast. It devoured memory and you couldn’t really do anything else with the host, but you got the Java ecosystem, for better or worse).
There was a lot of good tooling that is missing from other platforms, but also a ton of overhead that I am happy to not have to deal with at the moment.
With the JVM you basically outsource all the work you need to do in C/C++ to optimize memory management and a typical developer is going to have a hell of a time beating it for non-trivial, heterogenous workloads. The main disadvantage (at least as I understand) is the memory overhead that Java objects incur which prevent it from being fully optimized the way you can with C/C++.

So — Fastest at what, exactly? — is unanswered.
