How much speed improvement would you expect to get that way?

MzScheme isn't slow:


Well, it's still slow on programs that use continuations at a very fine
granularity. Otherwise, the gap between MzScheme and
performance-oriented implementation has closed considerably, especially
for the benchmarks that are supposed to represent real programs (e.g.,
"dynamic"). I see no particular obstacle to closing the gap further.

It's difficult to know whether these benchmarks measure anything that
you care about, though. Maybe you have some code that runs much faster
in Larceny than MzScheme? If so, I'm interested to take a look.
