pystone: pydotorg's RPM scores better than Fedora 2's RPM

Hi,

I find the pystone varies between the python2.3 from pydotorg  
(www.python.org) and Fedora Core 2's bundled python. But the highest  
pystone is obtained from rebuilt RPM from pydotorg source RPM. I use "rpm  
--replacefiles" to install pydotorg RPM on FC2. Fortunately, those  
python-based system config tools still works.

Here's the pystone score:

os,   python-version,        low,   high,
-----------------------------------------
FC1,  2.2.3-fc1,             22321, 23923,
FC1,  2.3.3-pydotorg,        33557, 35971,
FC2,  2.3.3-fc2,             28248, 29585,
FC2,  2.3.3-pydotorg,        32467, 33112,
FC2,  2.3.4-pydotorg,        31446, 32894,
FC2,  2.3.4-pydotorg-src,    35461, 37037,

Test condition: Dual Xeon 2.8Ghz, 4GB RAM, hyperthreading on, no cpu  
binding (no diff if cpu bound)


The difference in the source rpm spec file is:
- pydotorg disable ipv6 and enable pymalloc
- FC2 enable ipv6 but does not specify enable/disable pymalloc


Is the pymalloc that improve the pystone score? What is it?
