The benchmarks on the fourmilab page were done over a period of time and
when I last messed with running the benchmark in ST in late 2014, there
were discrepancies in the relative times.

usp=sharing
has a folder with a spreadsheet with the results I got then along with an
mcz with the benchmark for Squeak 4.
