I don't want to belabor the point, but I think that it depends; we
can't easily write "fast" under case-lambda and "slow" under
match-lambda or the like without talking about specific
implementations.  The portable case-lambda implementation from R7RS
also expands to (lambda args ...); given the possibility that someone
will run code on a Scheme using this, I wouldn't be particularly
worried about trying to optimize argument-matching in portable code.
