Just for the heck of it, I checked my CPU usage again just now,

177MB is not CPU, it's memory, and 177MB doesn't seem all that
much. Mine
is using 340MB for example. But then my machine has 2GB total RAM.
Sorry, I don't get the semantics right half the time. I have 1GB RAM,
and 177 MB seemed like a lot to me. :)

My question might be "If you've got 1GByte, why is your system not
using
1GByte??"
Why do people want lots of memory but complain if their system dares to
use it??
Daniel
He didn't say his system was using 177MB. He said SM was using 177MB.
O.K. then the question should be "If you've got 1GByte, why is your
system not using all its 1GByte to run SM??"
Daniel
It shouldn't. The system be it Mac, Window, Unix, Linux, BEOS, NextStep,
should have number one attention. Then any applications should divvy up
what's left over. And the should completely release for use by other
applications or the system as needed. In Practice though most
systems/applications they grow as needed but don't shrink. once they use
a certain amount they will be allocated that amount until the are closed
and quit and then reopened. Off loading memory on to hard drive slows
down computing by a factor of the drive speed. If You can have enough
memory (RAM) so that the system and any applications never use the Hard
drive then the computing becomes fast and efficient. The more Caching is
done on the Hard drive the slower things go. According today's System
Sizes and application sizes (memory usage) we need now a minimum of 8GB
just to do every day computing without getting bogged down.
You're quite right, Phillip, if SM is not the only program running, it
should be able to share RAM (and disk cache, if need be) with any other
programs running.
Same with clock cycles, share them to!
But if SM is the only program running (and, in this case, when I mention
program(s), I mean the thing(s) I have started up AFTER the computer is
up and running), then it should be able to make use of the total
remaining resources (RAM and cycles) without raising eyebrows!!
