I have helped develop a set of approximately 15 separate worksheets for
journal entries that feed into one master worksheet. We use a new set of
files for each day of accounting entries.

I use the search and replace function in the master file to update all of
the formulas (almost 4,000 formulas) to look at the correct day's entries. I
can do this fine on my PC, which is what I used in creating the original
files. In searching and replacing over the entire document, this takes
approximately 1-2 minutes.

However, when trying to perform the same task on a separate machine on the
same network, this process takes 5-6 hours to complete. I have verified that
both machines are using the same version of Excel and patch sercurities as
far as I know.

Any other suggestions on how to speed up this process?
