As with everything, this is a huge oversimplification (i.e. Go = faster than scripting languages). I'm dubious if the algorithmic part of static site generators dominates. Would have though it's I/O bounded to some degree, in which case Go isn't going to be faster than anything else. Besides, caching solves this issue better, unless you change the underlying templates.
