2918.0. "PEswitch 900TX performance?" by CGOOA::CRICK () Fri Oct 27 1995 18:13

    Is the forwarding perfomance of the PEswitch 900TX the same as the 
    DECswitch 900EF?

    Yes, insofar as the forwarding engine code used. The primary 
    difference between the two products is that the PEswitch 900TX is 
    sold as a desktop Personal LAN solution, and as such only has a
    64 node address table. The DECswitch 900EF is sold as a Departmental
    LAN solution, and as such has an 8000 node address table. Other than
    the address limitation, the store & forward algorithm is the same.
    The address limitation however precludes using the PEswitch 900TX
    as a network backbone traffic handler, as the 65th node or more seen 
    by the PEswitch would be flooded to all other PEswitch ports bringing
    down the performance. So if the PEswitch is used in its proper place
    in a LAN application/solution, it performs its duty nicely of bringing 
    10mb bandwidth to the desktop without any hitch in forwarding or
    latency.
