Edit: Added java

It looks like Go 1.1 might be faster than Java. That might help convince enterprise developers to adopt it.

Added java to the list. It's still faster then go.

No way would a microbenchmark ever change any responsible person's mind about tooling. There are a lot of reasons (some of them nearly respectable) to use Java; "it's faster than <X>" isn't one of them.

Don't be silly. Java is extensively used for speed. It is an extremely fast language with a few caveats (such as startup/warmup time).

Of course, I didn't mean to imply that any microbenchmark would change someone's mind. It's kind of absurd to think that's what I meant. Go should approach C/C++ in performance and often Java is promoted as about 2x slower than these two languages. Fast compilation and linking is another big plus. The formatting consistency is another. It's not a verbose language either.

Just curious, are you factoring in the VM warmup time for Java?
