Dear Gambit list:
I started a draft of a note about scheme benchmarking, in the specific context of the Gambit benchmarks, Larceny's R6RS benchmarks, and the R7RS benchmarks on ecraven's site.
I'm not terribly happy with it as it stands, so I don't know how much more I'll develop it, but I'm soliciting comments on the current draft.
It can be found at
