[plt-scheme] Performance Difference (209 -> 301)

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I recently updated the "Great Computer Language Shootout"  
installation of MzScheme from 209 to 301.  I thought it might  
interest you to see how things stack up with the new compiler.  As  
you can see from the results, the new 301 environment is nearly twice  
as fast as the 209 series, and the compiler is slightly better (in  
most cases).

So, I think Matthew (and the other implementors) deserve a big round  
of applause!

Thanks,
