[Tutor] performance

[Carlos Daniel Ruvalcaba Valenzuela]

Don't worry too much for the accessors, I'm pretty sure it won't
degrade your performance in a noticeable way, you objects will only
grow a tiny bit by adding a function to the class, all objects share
the same in memory code and each one has it's own data, the function
for the object is just a reference for the class function, not the
memory of the function itself (I think, it would be a waste of memory
otherwise).

However take it with a grain of salt, do your own benchmarks, you
could do a simple measure with time.time() function, or use one of the
several profiling modules for python (profile, hotshot, etc).

Forwarded to Tutor list, I forgot it sorry!
