It looks like your algorithm really does iterate over all values for
six variables and do lots of math.. then you can't do any better than
implementing the inner loop in C. It does look like you have some
functions that are being called that are also in python, and it would
be interesting to see i

In probably order of efficacy:
1) Use a better algorithm
2) Replace 'for'
Quick tip-
Try xrange instead of range. This will use dramatically less memory
if your search space is large, which will speed things up /if/ your
machine is being forced to swap.
Besides that, without seeing the code for your functions, it's hard to
offer more advice. Your algorithm is necess

The reason why I'm using six nested for loops is because I need to find
the best output using those six variables as input.
Here's the simplified code:
for per in range():
~for s in range():
~for t in range():
for v in range()

You may want to read through this case study by the BDFL.

Without seeing any code, it's hard to tell, but it's not a wild guess
that 'six inside for loops' may be replaced by more efficient ways ;-)
