RFC3081 specifies that TCP transport should send SEQ messages to remote peer to notify it about local frame sizes. When these messages are used, TCP channel will protect itself against one channel domination - where other channels wait until one channel with most data finishes its transport.

When you connect to different BEEP implementations, you should leave this property to True (default value). However, if you connect only to wodBeep peer, and you use only one channel, you can set this property to False - and improve communication speed.
