you *cannot* use the profiler to measure overall execution time; it's
designed to let you know where the program spends most of its time,
not to compare different algorithms.

use 2.3's timeit script, or write your own timing loop.  with timeit, I
get these results:

> python timeit.py -s "import string; text = 'ben at orange?enter&your&code';
delete = '@&'; table = string.maketrans('', '')" "result = text.translate(table,
delete)"
100000 loops, best of 3: 13.9 usec per loop

> python timeit.py -s "text = 'ben at orange?enter&your&code'; delete  = '@&'"
"result = text" "for c in delete: result = result.replace(c, '')"
10000 loops, best of 3: 48.4 usec per loop
