There is a benchmark test which includes the 'computer language benchmarks game' (aka language shootout) programs in the Go source tree under go/test/bench/shootout Last time I checked GccGo won most of them hands down and even more so when you changed the optimization from -O2 to -O3 (on my machines atleast 'i5/i7' -O2 always lost to -O3 in these tests so I don't know why they defaulted to -O2 here). This was on 1.03 I think, I haven't checked on 1.1x as of yet and given that there's been improvements in the Go compiler the overall results may have changed considerably.
