>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... >discover a new interest in D, C or Erlang >where performance is a consideration Erlang on The Game: http://benchmarksgame.alioth.debian.org/u64q/benchmark.php?test=all&lang=go&lang2=hipe&data=u64q 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.
