Your loop only seems to dials the server once, then reuses the channel from
/srv. 9fs(4) is just a convenience wrapper for common hosts and tasks that
ultimately calls srv(4) and mount(1) as necessary - if the channel exists, it
is simply a call to mount(1), which translates to an attach(5) 9P message on
the existing connection.
Delete the channel from /srv in the loop to test a full remote mount dance,
including the initial dial. It shouldn't take 3s to dial, though.
