Richard Jones' Log: Shiny new hardware, obpystone

Wed, 23 Feb 2005

The old (at least 5 years old dual P3 860MHz):

$ python
Python 1.5.2 ...
$ python /usr/local/lib/python2.3/test/pystone.py
Pystone(1.1) time for 50000 passes = 5.16
This machine benchmarks at 9689.92 pystones/second

*cough*

$ /usr/local/bin/python -V 
Python 2.3.4
$ /usr/local/bin/python /usr/local/lib/python2.3/test/pystone.py
Pystone(1.1) time for 50000 passes = 3.87
This machine benchmarks at 12919.9 pystones/second

The new (both machines have dual Opterons at 1.8GHz):

ellis:~$ python -V
Python 2.3.5
ellis:~$ python /usr/lib/python2.3/test/pystone.py
Pystone(1.1) time for 50000 passes = 1.17
This machine benchmarks at 42735 pystones/second

gaiman:~$ python -V
Python 2.3.5
gaiman:~$ python /usr/lib/python2.3/test/pystone.py
Pystone(1.1) time for 50000 passes = 1.16
This machine benchmarks at 43103.4 pystones/second

Oh, and:

gaiman:~$ python -c 'import sys;print sys.maxint' 
9223372036854775807

Cooool.... :)

Updated to correct speed of new CPUs

They're actually 1.8Ghz Opterons :) (Or close enough...)

For the record, my home machine (Athlon XP 2800+, 2GHz) gets about 42k as well.

E:\>c:\python23\Lib\test\pystone.py
Pystone(1.1) time for 50000 passes = 6.67537
This machine benchmarks at 7490.22 pystones/second

*schniff* :'(

C:\Python23\Lib\test>python -V
Python 2.3

C:\Python23\Lib\test>python pystone.py
Pystone(1.1) time for 50000 passes = 1.26348
This machine benchmarks at 39573.4 pystones/second

On a athlon 2600+. You'd prolly get a decent speedup if the program was multithreaded.
