That sounds fair enough and I would have done it except that
dos.time() returns a value of something like 4.8 seconds, but it
doesn't include the 10 minutes I was waiting for the hourglass to
finish. Running the same code in Unix would have a unix.time of
something like 7 seconds. Comparing the "objectively measured" times
does not give a sensible comparison. If I can see that I can start
doing something else in Unix in less than 10 seconds, but need more
than 10 minutes in NT, I believe my subjective measurement and
distrust what was being measured by dos.time().

I brought up this question last year and it didn't seem to be common
to others. There's a bottleneck somewhere that doesn't affect Word
and Excel and I don't really blame S4 for it. I haven't had the time
to seek it out thoroughly. I need to borrow other equipment to test a
few things to track it down.

Cheers

Patrick
