Focusing on on performance, seriously?

I'm more sysadmin than devops, but how fast you can script over something for a quick automation is the defining trait for most devops tasks, not performance. Going for performance is closer to dev than to ops. Using APIs of several systems doesn't need so much performance neither, unless you are doing pretty intensive amount of calls (and the backend/network could be more of a limitation than the language you use in your side).

Yes, the performance and one-file-deploy are Go advantages against python performance (not for that much) and dealing with dependences and versions. But that is not the whole story, at least for most of the tasks I had to deal with.

And it is not "or". You may want to decide between python or i.e. perl for scripting language used for automation, but there are things that should be addressed with python, and others with go.
