In /opt/coolstack/bin

No idea how much (if any) it'll help, but I'd be eager to hear.  -Tim

That's nice. I thought coolstack did not have a Python build.

I'm also going to try to run with Stackless Python, I hear it's good  
for threading.

Interesting. It may be making a /slight/ improvement over my
home-built 2.5 32 bit on O.10m, but probably within the margin of
error. Strangely, I'm seeing faster results on my 2.5 than previously,
so I'm going to have to do some more digging.

There isn't much between the Coolstack version of 32 bit 2.5 and mine,
but it seems slightly in its favour. Over the times we're talking
about for the top of the WF-2 table, the difference will be in the
seconds (around 1-2%); Coolstack versus the built-in 32 bit 2.4.4, I'm
seeing a 10% improvement, so that's a big win.

So that's probably caused by a faster interpreter in Python 2.5?

I'm guessing a combination of improvements in the interpreter itself
along with algorithmic improvements in the built-in libraries and
types.
