What could be a possible reason why in a three switch setup-all attached to one router(a 3640) would the first switch pass outgoing traffic better(faster) than the other two. All are set up the same, using the gig uplinks, same default gateway(the router) and default settings? ie on a streaming video coming in to the office the first encodes at 245kb while on the other two it's at 22k ? Clearly there is some type of bottleneck here-any ideas??
