When I worked for Amazon, someone had created a command line tool to be used in builds, but repeatedly starting up JVMs is painfully slow. I rewrote the app in C++ and it could be invoked 81 times vs one invocation of Java version.

If I need speed, I'll use C++. If I need developer productivity, I'll use Ruby.

Why in the world would you rewrite it when you could take an hour and get it compiling with graalvm and it would be just as fast as c++?

So, Java is fast if you use it like C.
