Hi, we have a very large spreadsheet which takes 15 minutes to recaculate.
We were running on a Core 2 Duo processor which task manager shows is
utilizing 50% of the processor. On a brand New Zeon Processor it now shows
that it is utilizing only 25% of the processor.

This is the only task this PC has to perform, 24 hours per day x 7 days per
week. Is it possible to utilize the entire processor to speed up the recalc
somehow?
