>It's been around 2x faster than Python in most of my uses
You must have some very unusual uses for that to be true. The computer language shootout isn't perfect, but it includes a variety of uses, and python is at best 5 times slower than go on benchmarks actually written in python instead of C, and 20-30 times slower for most of them.
Go is in the same performance field as java, haskell, scala, lisp, C#, etc. The 2-5x slower than C group. Python is in the same field as php, perl, ruby, etc. They are 30-50x slower than C. That's a huge difference.
