Go 1.1 performance improvements, part 2

It's nice to see someone actively measuring this stuff and talking about regressions and gains in a concise manner.<p>Definitely looking forward to the final article in the series!

Call me a spoilsport, but it's still slower than Java <a href="http://benchmarksgame.alioth.debian.org/u32/benchmark.php?test=all&#38;lang=java&#38;lang2=go&#38;data=u32" rel="nofollow">http://benchmarksgame.alioth.debian.org/u32/benchmark.php?te...</a> . That takes the bloom off the rose for me.

Do most people using Go in production use the Plan9-derived Go compilers or GCC? Are there any realistic programs where the Plan9-derived compilers generate better code?

Does anyone know if Go will generate AVX instructions?
