I've read the EULA, it's mostly about best/fair practices when releasing benchmarks to the public. But having this codified in the EULA must give legal departments the shivers! I'm surprised there are no perf benchmarks on the web comparing Go....to anything! The last I heard they were way behind even the JVM on perf; just because they ahead of time compile doesn't give them much of a natural advantage here (since JIT compilation is not a perf problem in practice).

.net has value types that you can use to avoid allocations. I've used them to write GC free code before where it's necessary, like doing a physics engine. I'm not sure if this is comparable to how you are avoiding GC in Go.
