We are testing WAAS in one of our branch offices. It is a small office with about 8 people. The office has a 2Mbps WAN connection with a latency back to the main office of around 80ms. We are using the Enterprise license with CIFS enabled. Everything seems to be working very well except for MS Office 2003. We can copy documents down very fast (files were prepositioned) but when we open a file with Word/Excel, etc, it will load pretty quick, but there is a substantial delay before any changes can be made. If we go as far as adding one character (such as a space) into a document, then attempt to save the document, once again there is an incredible delay. We understand that the Office products are writing to a temp (.tmp) file in the share while the file is open in the application, is this what is causing the delay? Can this not be optimized somehow? Is there something I'm missing?
