Subject: Re: [Pythonmac-SIG] 2.4.3 Python Universal Binary Pystone Comparison
Ok, I see what the problem is, because the Universal python is also half as fast on my PPC.
It appears that the universal build is not using any compiler optimizations at all, where a normal build is -O3. I'm not quite sure where/why this is happening (autoconf is evil), but I'm sure someone will figure it out soon enough.
# universal
OPT= -DNDEBUG -g
# normal
OPT= -DNDEBUG -g -O3 -Wall -Wstrict-prototypes

Hmm. Here's three of those...

Nice. Very jealous about the Intel MacBook Pros. :) You both better put them to good use! ;)
Have either of you tried building the 2.4 release branch and running pystones from it?
For those reading who may not know how from Terminal::
svn co http://svn.python.org/projects/python/branches/release24-maint py-24
cd py-24
./configure
make
./python.exe -c "from test.pystone import pystones; print pystones()"

I was just wondering if anyone else had compared pystones on their box? I downloaded the latest Universal Build from the python.org and found things to be a bit sluggish. So I ran the pystones test to quickly gauge things, and noticed that things are indeed running about 1/3 of what they should be. (Specific info from the Terminal below.) Anyone have ideas? They both appear to be built from GCC 4.0. Let me know what other information you need from me.
Also, are there build instructions for creating the Universal Packaging?
Thanks,
