[Python-Dev] L1 data cache profile for Python 1.5.2 and 1.6

[Neil Schemenauer]

Using this tool:

    http://www.cacheprof.org/

I got this output:

    http://www.enme.ucalgary.ca/~nascheme/python/cache.out
    http://www.enme.ucalgary.ca/~nascheme/python/cache-152.out

The cache miss rate for eval_code2 is about two times larger in
1.6.  The overall miss rate is about the same.  Is this
significant?

I suspect that the instruction cache is more important for
eval_code2.  Unfortunately cacheprof can only profile the L1 data
cache.  Perhaps someone will find this data useful or
interesting.
