Not only that, but although the particular test described in the linked blog post did not include database connectivity, we saw a massive increase in database performance in 1.1 versus 1.0.2 due to a fix in the sql package [1]. That was back in Round 4 of our project [2].
Just something to be aware of if anyone reading has Go 1.0.2 installed and has not yet upgraded. 1.1 is worth the upgrade.
