In my experience, I would think (note I am just guessing here) that
the compiler has actually been optimized for intel way back when they
started doing Windows.
Without having any numbers to back anything up, I have always felt
that my app was significantly faster on Windows than it was on Mac
G4. I have a Power Book 17" 1 GHz (and a Mini 1.42GHz) and a Dell
laptop with centrino 1.6 GHz, and the Dell has always felt much
faster doing my application, which is quite heavy, doing mostly
recursive database searches. But this also might just be a perceived
speed difference due to the fact that the mac only shows you windows
that are fully drawn, unlike Windows which shows you the window while
it draws.
I had one of those perceived speed differences some time ago, when I
was testing mySQL vs SQLite. mySQL seemed quite a lot faster, but
when I benchmarked it, SQLite was actually significantly faster.

Me neither, I am just curious.
I guess you mean one real process ( my app doesn't use threads
anyway) . I
do get the feeling that even accounting for this that the RB compiler
probably isn't optimizing as much as it could ( if at all ) for
Intel. It
seems the only speed benefit I am seeing is due to the increased
clock speed
( this would account for around 1.7X ) . The memory bus is also
significantly faster than a PowerBook - that would account for the
remaining
33X factor.
The conclusion I make is that the change in CPU architecture has
made NO
difference to the running of a single threaded natively compiled RB
app.

I really don't want to disagree. But since almost all RB Apps only
use 1 real thread, you will not gain the real speed a 4 core machine
has to offer. You will only be able to use 100% of one core.
The real speed of these machines is in multithreads.

The latest MacPro's are seriously fast machines, even as Wintels.
Check out the following link:

fastest-pc-in-the-uk.html
This PC magazine tested a MacPro with two Xenon Core Duo processors
running at 3 GHz and XP. It was the fastest PC they had seen, ever!
Therefore, RB_UB application should have been very quick.

That's my point. I have the Latest machine, 4Gig ram, 2.66 gig
clock,
And compared to my PB 1.5 ghz - ie same spec roughly as your mac
mini - I am
not seeing any reall kicking of the proverbial bottom. ( unless
you consider
a X2 speed improvement a serious kicking of the rear... )

You can not really compare these machines.
