We have a problem where when our wan circuit fills to almost 100%, file/folder browsing becomes very slow. Maybe 15-25s to open a folder. So a user could wait 60-100s if they have to drill down 4 folders. Users are complaining a lot when this happens. It's becoming such a problem that upper management is questioning our investment in cisco waas.
Anyone else notice this behavior? Is this normal?
It doesn't seem like I should/could solve this with qos (we already have qos for VoIP and SAP). It also is not practical to upgrade all our circuits. The circuit would probably still fill to 100% at times even if we doubled our bandwidth everywhere.
