I suspect there are other folks who have run the pie-con benchmarks on their machines. Perhaps we should construct a chart. Times below are in seconds.
~60 Guido's ancient 650Mhz Pentium ~27 Guido's desktop at work ~15 IBM T40 laptop 88.550 dual 450 MHz Pentium 2 22.340 Athlon XP2800 (1243.363 MHz clock) The latter two times are for Python 2.3.3 built out of the box using the Makefile (make time) shipped with the parrotbenchmarks ftp file on an unloaded machine. The times reported are the user time from the time triplet.
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. :-)
