I couldnt help with your other questions but I thought I might try to help with this.

I wasnt entirely sure what you meant but thought this website might help:
http://www.onlamp.com/pub/a/python/2005/12/15/profiling.html

or the page from the python library site:
http://docs.python.org/lib/profile.html

sorry if I completely misunderstood what you wanted!

This is a very basic example which demonstrates the python profiler:

import profile

def counterTest():
    """Count from 1 to 100000 using the
    append instruction
    """
    Counter = []
    for i in range(100000):
                Counter.append(i)
    return Counter
        
print "Profile for counterTest, print the CPU time it took to count from 1 to 100000\n"
profile.run('counterTest()')

The output looks like:

Profile for counterTest, print the CPU time it took to count from 1 to 100000

100005 function calls in 1.226 CPU seconds
