Perhaps we can turn this into a benchmark comparison chart.  In
particular, in my experience pystone is a pretty good indicator of
system performance even if it's a lousy benchmark.  I'll report the
pystone numbers for those same three systems:

home desktop: 10438.4 pystones/second
work desktop: 17421.6 pystones/second
laptop:       30198.1 pystones/second

Multiplying the pystone numbers with the parrotbench times should give
a constant if the benchmarks are equivalent.  But this doesn't look
good: I get

home desktop: 626304
work desktop: 470383
laptop:       452972

The home desktop is a clear outlier; it's more than twice as slow on
the parrot benchmark, but only 2/3rds slower on pystone...

(This is begging for a spreadsheet. :-)
