The Dhall Configuration Language
> jsonnet seemed like a great idea to me, but I've experienced extremely low performance.
Although each implementation of jsonnet has some quirks, take a look at (scala-based) sjsonnet^1 or go-jsonnet^2 for improved performance. We use go-jsonnet because of some issues we had with the scala version - but it does seem to be the fastest by a large margin.
There's also a Rust version^3 that claims to be the fastest yet^4, but I haven't experimented with it at all.

Is GO a good option to write a compiler/interpreter?
While I never wrote one, there are some good examples out there beyond the Go compiler itself. Have a look at the Benthos bloblang one (which is quite simple): https://github.com/Jeffail/benthos/tree/master/internal/bloblang and the go-jsonnet VM one (which is more complex): https://github.com/google/go-jsonnet
