I haven't tried it myself but I would have expected the short, intense
jobs generated by compilation to be a problem.

Yes, I've been meaning to add that to the benchmark tool.  I'll let
you know.

In informal measurements it seems to be quite reproducible.  The sd is
typically only a few percent of the overall time.  But that might be
an interesting option to add too.
