Re: [Visualpython-users] visual 5.0 speed ?

I think Bruce meant the following to go to the list (sorry Bruce if it 
wasn't):

Actually, it was also the case in Visual 3 that setting the rate too
high could slow down the animation loop. Probably depends on the details
of the particular program.

It would be useful for those interested in these issues to post
relatively simple examples with compute times, and say what the
hardware/software environment is. The standard scheme looks like this:

from time import clock
....
t = clock()
.....Do Computations
t = clock()-t
print t

Make more than one run with a program and average the results because
you'll observe fluctuations, presumably associated with other random
stuff the operating system is doing. In my own measurements of this kind
I've seen little difference between Visual 3 and Visual 5.
