[AFMUG] RB1200 ports 9&10

[Adam Moffett]

I just read a forum post saying that ports 9&10 on the RB1200 
underperform compared to the other ports.

Does anyone know how bad that underperformance is?  I've been pulling my 
hair out for days chasing a performance issue on a backhaul, and it 
turns out one end of it is plugged into port9 on an RB1200.

Could it make my 200 meg link only do 90meg?
