The master will detect it quicker, because it will get an error when
it tries to send something.
But the standby should detect it either when sending the feedback
message (what's your wal_receiver_status_interval set to?) or when
ythe kernel does (have you configured the tcp keepalive on the slave
somehow?)
Oh, and what do you actually mean by "long time"?
