Are there any known issues with speed between excel 2003 and 2010 when using WAAS?

Request asked by customer. Thought I would run this by the forum first.

Can you please raise a ticket with Cisco TAC asking why Excel files in 97-2003 file format cannot be fully optimized when compared to the same file being saved in the latest file format?

When using the latest file format, the user experience is amazing and up to 100x faster to open and save files. Our testing has identified an issue with the older file format.

I deployed WAAS about 3 years ago. Part of the deployment was before and after testing. When the users used Office 2010 the results were good. When they used Office 2003 the results were terrible. Some files took minutes to open, some never opened. Solution was to upgrade to O2010.

Hope this helps.
