Version 2.3.3 vs 2.4.2a Timings

C

Colin J. Williams

These timing results with Fibbonacci, using and not using memoize might
be of interest.

Version 2.3.3 - Unwrapped is using interation in place of recursion
C:\Test>python tFib.py
Unwrapped, using fib: 7.52 usec/pass
Raw Fibonacci: 252.66 usec/pass
Fibonacci with old deco: 3.18 usec/pass

Version 2.4.2a
C:\Test>\Python24\python.exe tFib.py
Unwrapped, using fib: 4.92 usec/pass
Fibonacci, using @memoize: 2.89 usec/pass
Raw Fibonacci: 214.11 usec/pass
Fibonacci with old deco: 2.90 usec/pass

Conclusions:
2.4.2a provides a significant speedup for these cases.
The unwrapped approach is much better than recursive fibonacci, but not
as good as with memoise.

This is based on Dan Bishop's code.
