That's exactly what I thought, too. But, to my own surprise, it's as fast as CGO solutions, in most cases even faster. You may check here: https://github.com/cvilsmeier/sqinn-go-bench
As with all things software: you can't eat your cake and have it. This is a compromise which suits many use cases, but not all. I've experimented with the version that was translated from C to go, and it worked fine for me (low intensity service using the db for auth checks and logging). Sqinn-go will probably serve as well.
