I think you must mean bottleneck, and not collision. In a switch, the
collision domain is restricted to the NIC and the port it is connected to -
there is no collision between ports. In full duplex, there is no collision
because there is a direct circuit between send on the NIC, receive on the
switch port, and vice versa.
The question of whether there's a bottleneck is a question of traffic
analysis. How many concurrent data streams (and of what size) are there
between the resource node (server) and demand nodes (clients)? This can
only be determined be doing an analysis of the communication between the
systems involved?

| Using Catalyst switches will reduce collisions. Remember that switches

| Unles you have a reason to want more switches.
