Nice.

These are incredible. What input data was used for JSONEncode/JSONDecode?

Very good job!

@powerslacker, all the benchmarks are available in test/bench/go1 of the go repository

No metrics for XML encoding/decoding?

Good work :)

Thank you

You probably have to keep in mind that many of these are NOT compiler improvements, but that the library implementation has been rewritten for many of these features...
