I will post some of my test results here for each of the acceleration components.
The effectiveness of the compression algorithm will vary based on the traffic being sent. Data that is already compressed such as iso and zip files will not benefit much from compression. On a corporate WAN most files being opened by users are not in a compressed format.
This test was done by downloading large files over a roughly 4Mbps serial connection. I recorded the time it took to download and KBps with acceleration enabled and disabled. So far I have only tested HTTP traffic I will try to run similar tests on CIFS traffic soon and update this page with those results also.
No joke the Excel file was downloading at about 1.21MBps.
