That would be better. At least that would have firewire too :-)

I'm using the following Tom's Hardware chart for my calculations:

It seems that, using the motherboard, a 2GHz Celeron is about 20% slower
than a 2GHz P4. 

I can't really do the same comparison between a PIII and a P4 since they
never appeared on the same motherboards, but I thought that P4 was
slower than PIII, clock for clock, because to allow for higher clock
speeds, the P4 needed a very deep pipeline. Anybody know?

In other news, here are some VERY old pystone results:

These are the most resent pystone 
Celeron 500 (FreeBSD 4)
Pystone(1.1) time for 10000 passes = 1.72
This machine benchmarks at 5818.18 pystones/second

G4/400
Pystone(1.1) time for 10000 passes = 1.5
This machine benchmarks at 6666.67 pystones/second

Quartz is remote displayable.

The Mac OS X display server renders streams of PDF sent by the
application. Where you would layer X in such a scheme? Above X so you
pay a massive performance price converting high-level PDF primitives to
low-level X primitives or below it so applications are reduced to using
X primitives?

Here is a brief overview of Mac OS X graphics:

No, they used DPS without X.

Nope.
