There are several things to look at, the first one I can think of is the send window size on the switch ports that go to the MPX110. It has to be adjusted to the distance, to allow more packets on the fly. If you have the distance set to "normal", then only a few packets will be sent and the switch will wait for the ACK to come back before sending more.
