You will always see some kind of collisions...
Minor ones are a given. And the differences in top speed is also a given.
You will lose some for overhead, and these speeds are in theory. Just like
if you had a 10/100 switch...you never get 100 thru put.
Get rid of your 10Mbit hubs and get gigabit switches and cards. They are
cheaper nowadays... You can get a 5 port for maybe $50. and cards for $15.
US (a switch doesn't share the bandwidth as a hub does.)
cat5 cables will work.
