Understanding the Pystone measurement

[tleeuwenburg]

Hi there,

Is there a good writeup of what the pystone measurement actually
means? I'm working on benchmarking of some Python code at work, and
I'm interested in how Pystone might be relevant to me. I've tried
googling, but I can't find any introductory / definitional
descriptions of what this module/measurement means.

Any pointers much appreciated!

Regards,

Pystone provides an estimate of the relative performance of different
pieces of hardware running single threaded Python apps.

If your old laptop scores 12000 pystones and your new shiny macbook
scores 84000, then you can expect your non-i/o bound single threaded
python apps to run about seven times faster on the new machine.

I forgot to mention that PyStone is just a Python translation from C
of the venerable Dhrystone benchmark. See http://en.wikipedia.org/wiki/Dhrystone
for a short write-up on the history, purposes, and limitations of the
benchmark.
