When Go is involved, it is better to compare the 64bit compilers which are the ones used by almost everyone: http://shootout.alioth.debian.org/u64/benchmark.php?test=all&lang=go&lang2=java http://shootout.alioth.debian.org/u64/benchmark.php?test=all... Go is already faster than Java in half of the benchmarks, and uses dramatically less memory. Of the benchmarks where Java wins, at least one (regexp-dna) is not related to the language at all and only to the regexp implementation, the one used there is a toy, Russ Cox already has written a much better high-performance regexp implementation based on re2 for Go which should replace the existing one very soon.
