I recall preferring rsh to ssh when working on s390 for the very
same reason.
However, one useful feature of ssh (that did not exist at the time) is
that you can use one existing connection. In .ssh/config:
Host *
ControlMaster = auto
ControlPath = ~/.ssh/control/%h__%p__%r__%l
This means that the first connection to the system will have the full 15
seconds of handshaking. But the next one will simply connect on top of
an existing connection. I suspect it would even be less than the 1
second for the telnet connection.
If you have a number of simultanious connections, it may help.
Alternatively, start a single "control connection" when you start
working, and keep it working for as long as you need it.

Isn't shorewall rather famous for producing not-so-efficient iptabnles
rules?

You try to login (from telnet) as root? If so: see securetty and such.
