I thought that too, but I think the URL (bench.html) with the 6-year old version was just for the meaning of the columns. The new results were attached to the email, and presumably he used the most recent one.

Hi Brad: this is a 6-year old version of Racket you're using. FYI.

I downloaded 64-bit Racket and compared it to my install of 64-bit gambit:

This is a Mac Mini with a 2.4GHz Intel Core 2 Duo and 8GB of ram.
So this is a Gambit with special gcc options that I find generally makes code run faster, at the expense of compile time. And it uses the latest GNU GCC.
So this is not comparing stock gambit with stock mzscheme; it is not comparing apples to apples.
I applied Matthew Flatt's patch from
https://www.cs.utah.edu/%7Emflatt/benchmarks-20100126/log1/bench.patch
to Gambit's bench script, and then ran "table" from Gambit's bench directory.
This gave me the following four html files that summarize the cpu and real times to execute the programs; compile times are not reported (just because the "table" script does not report them).
The meanings of the various table titles can be found here:

I repeat:
So this is not comparing stock gambit with stock mzscheme; it is not comparing apples to apples.
The systems seem comparable running programs in R6RS-* semantics, except for programs using call-cc.
