[Using Jeff Carter's <carter@innocon.com> simple yet compelling
example with MachTen and gnat 3.07, Dave gets a shade under 5
seconds per run.]

Using gnat 3.07 with the same options on a 120 MHz PowerPC 604, I
got an average execution time of 4.05 seconds. On a 180 MHz PowerPC
604e, Jim Hopper reports an average execution time of 2.32 seconds.

Both our results are less variable than Dave's, probably because
we're using Tenon's CodeBuilder product. The latter doesn't include
MachTen's inet stuff, so it's may have less overhead.
 
"Since the processors are comparable, I suspect the most improvement
in time is because of 3.07.  I no longer have 3.05 installed, so I
can't check the timing with it."

The clock speeds are comparable, but the 604 and 604e are more on
par with the P6. Like you I don't have 3.05 handy, but my other
tasking code didn't improve at all with 3.07; there's more to it
than that.

"Anyway, not too shabby."

Indeed!
