Hi!

Sorry, I don't have an answer for you but I am curious to
know just how long the calc time is?

I have a Gateway PC that has a Pentium 4 processor that
uses
hyper-threading. The manufacturer advertised the machine
as operating at
2.8 GHz. What I think this really means is that there
are 2 1.4 GHz
processors.

Most applications seem to make appropriate use of the
hyper-threading, so
the PC is normally pretty quick. Unfortunately, Excel
does not.

Some of the spreadsheets I work in are really large (40
MB or so), with lots
of array formulas. When one of these is recalculating,
it takes a really
long time. If I start Task Manager and check the
processor load, it tells
me that only 50% of the available duty cycle is being
used -- all by Excel.
This leads me to believe that Excel is not using both
processors.

Does anyone know if there's a way to force Excel to use
all of the
processing capacity of this machine?

For what it's worth, I'm running Excel 2003 on a Win XP
Home SP2 operating
system.
