[Twisted-Python] Python SSH Server( twisted.conch) takes up high cpu usage when a large number of echo

    I write a SSH server with Twisted Conch. But encountered a difficult problem. Assume that user A and user B log in to the twisted ssh server through ssh command. Then user A tail or cat a large file (greater than 100M) on the server, which will cause a lot of echoing through the twisted ssh server, making python ssh process (twisted.conch ) cpu usage is very high (greater than 95%, or even 100%), then the user B will be blocked, a long time no response. Is there any way to sleep userA's session(0.5 seconds) when find the user A has a large number of echo through the twisted ssh server and not blocking the other connected users?
