    >Go is significantly slower than the rest, much much slower.

Everyone knows that Go is a new-ish language and has room to improve on performance. That said, Go seems perfectly fast since all of the languages seem to perform fairly well.

Further, were Go "much much slower", CloudFlare, IronIO, Google, etc would probably not be using it...

Erlang on The Game: http://benchmarksgame.alioth.debian.org/u64q/benchmark.php?t...

Go looks to be about ~50% the performance of C++, but, from lots of peoples' comments/writings, is much nicer to write so they use it when productivity is more important than absolute performance.

Note: I'm interested in Go (as I am about lots of languages), but am not a user of it right now.

Ya, Erlang doesn't do well on the Benchmarks Game because the Benchmarks Game doesn't measure communication, which is Erlang's strong point. No-one writes algorithms like those in the Game in Erlang; you code them as a server in C or Java or anything and farm work out to them from Erlang.

The Game is a terrible benchmark for Erlang. Math, computing digits if Pi, string searching, n-body problems. If that is the target domain, don't pick Erlang, or Go, pick Fortran or C.
