I have any queue to consumer message, just publish, connection is in "flow" state, channel is in "running" state.
 If i add a queue to consumer message, the connection and the channel is all in "flow" state.

Flow control does not depend on CPU usage but rather whether consumers
can keep up with producers. Try adding a consumer.
