Guile benchmark

[Rchar]

Hello,
I wanted to compare Guile scheme to other scheme implementations and I found 
this:https://ecraven.github.io/r7rs-benchmarks/benchmark.html

Is Guile slow or fast, comparing to others?
Is Guile scheme slows down entire GuixSD (If Guile speeds up, GuixSD also 
speeds up)?
Recently I found scheme compared to C, is it even possible?

Please help answering these questions, and share your opinion.
