It could easily have played it. Remember I published my comparative results on
my 624 MHz PDA as being roughly 15 times slower than my Athlon at 2GHz? This is
65+% slower than that same PDA.
The problem is that you see the 0 seconds and somehow presume it must be similar
after all zero times 15 is still zero. My testing showed that those fractions of
a second can easily be 0.7 or 0.8 seconds for example, so multiply that by
40-50, add to that the time trouble, and it becomes VERY believable.
