The setRequestedFrameMax() method negotiates the *maximum* frame size,
not the default. AMQP peers may exchange tiny frames containing tiny
payloads, even at the default framemax of 128Kb.
Setting the framemax to the lowest allowed value (4Kb) will reduce
throughput if this causes fragmentation for a significant proportion of
messages. Latency might be slightly better though. Benchmarking is

There are no broker config variables that control frame size. AMQP is
already a very slim protocol. You don't need any further configuration
to take advantage of this!
