That's very interesting, Rob. Were the apps compiled using the same
compilers (with the same degree of optimization) in both cases? Were
the time differences actual CPU time of just elapsed time?

Warren,
I'd concur. This application was hugely floating point
intensive. Graphics ops were not an issue for us. The app used only
low-level X11 calls (no Motif, or Xt calls even), so what graphics
there were under OSX had to go through Apple's X11 layer before being
seen. Most of th
I think one needs to distinguish between the OS and the CPU. My
experience with the G5 is that its floating point performance is
between 1.5x and 2x as fast as the equivalent x86. Unfortunately, the
fixed point advantages are not there. I use LaTeX a lot and heard that
