Java is Very Fast, If You Don’t Create Many Objects

  • 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.
