Does anybody have figures for obtained packet rates for asynchronous
terminal concentrators over ethernet?

I mean the configuration where the host has an ethernet interface and
lives on the same LAN as the asynchronous terminal concentrator which
supports say 8-16 terminals.

I think DEC has a product of this type called LAT (LAN Asynchronous
Terminal?).  I would suspect that because protocol layers 3 and 4
would not need to be implemented that better performance would be
obtained than with telnet or rlogin based terminal concentrators
(although internetting would be impossible).  I would still be
interested in figures for telnet or rlogin style terminal
concentrators as well.  Also while the maximum packet rate at the
concentrator is of interest, I would really like to know what sort of
packet rates people consider good on the host side.
