That sounds like a pretty large file for such a small amount of data/formulas.
Do you have any pictures in the workbook?
Do you have any event macros in the workbook?
Do you have lots of conditional formatting?
I bet if you copy each sheet and paste|special formulas into new worksheets in a
different workbook, the speed will increase and the size will go down.
If you have macros, you'll have to copy them, too--sames with names, page setup
and all those things that you won't remember until you do it the second or third
time!
And here are a couple of sites that discuss slow performance. The first is by
Charles Williams and the second by David McRitchie:

And one more thing...
Do you have Google Desktop Search installed--or any of those search programs?
Try disabling them to see if that helps.
