The JVM is really fast- but to be fair note the JVMs memory usage in that comparison. Also version of Go used in that comparison is Go 1.0.3 and Go 1.1 RC (which is much faster and has better garbage collection) is going to be out next month. Go is a very young language so while very fast compared to an interpreted language like Ruby, Python, etc by virtue of being compiled, it going to take some time be be on par (in terms of execution speed) with a Java, a JIT language that has had 18 years to mature. It says a lot for Go that its execution time is on par with C#: http://benchmarksgame.alioth.debian.org/u64q/benchmark.php?test=all&lang=go&lang2=csharp http://benchmarksgame.alioth.debian.org/u64q/benchmark.php?t...
