by having three subnets, you are causing traffic between subnets to be
twice as much as if they were a single subnet. This is because each
packet must goto the router, and then back out the interface to the
destination, which is all on the same collision domain........so that can
be bad for collisions for one. One way to solve this is to run an IGP so
that workstations can realize that the addreses are actually reachable
directly.

switch as much as possible, hub as less as possible :) Seriously, you
will have to first start by examining your traffic flows.
