Same Excel Coding runs fast in Win XP but very slow in Win 7 (64-bit) RRS feed

  • Question

  • Hi all,


    Our user has an Excel 2003 workbook with some iterative calculations.  It runs for 10 mins only on Window XP.  When they upgrade to Win 7 (64-bit), the same workbook runs for an hour.  It works but extremely slow.  Based on that, they try to run on Win 7 (32-bit), it finally goes to 20 mins.  As the workbook runs repeatly, the one-hour workbook turns to days overhead.


    i)  Any hints on the slow performance of Excel in Win 7 (64-bit)?  I have tried to save the Excel as 2010 format.  My Excel version is 1.0.6129.5000 (32-bit).
    ii) Any parameter tuned in Excel or Win 7 (64-bit) to improve the performance?  Our user has to run in Win 7 (64-bit) ultimately.

    Thanks a lot.
