Joe,

The 100msec of CPU time for a 3.3KB dynamically generated web page sounds
right.  But the 20msec of CPU time to display a 5250 subfile is much higher
than what I expected.  Frankly, I expected your CPU to use about 5 msec to
build and display a screen with a subfile.  It takes my machine about 25msec
to build and display a screen with a subfile, and I thought you had a CPU
that was more than 5 times the speed of mine.

Maybe I'm missing something.

Nathan.
