1978.0. "Help required..." by QCAV01::PMK () Tue May 20 1997 07:41

    Hello,
    
    We are facing the following problem at one of the customer site.
    
    The hardware details of the system
    
          Alpha Station 200 4/100 with
              32Mb ram
              1 x 1Gb hdd
              1 x CD-rom
              1 x DE205 Ethernet card.
    
          OpenVMS AXP V7.0
    
    Decservers are connected on both built in ethernet card and DE205
    ethernet.  customer is using process instrumentation devices 
    connected on Decserver.  
    
    File copy from the devices connected on DE205 ethernet card takes
    more time comparted to that of devices connected on built in 
    ethernet card.  The decserers are connected as shown below

    TS1 to TS6: Decservers to which process instrumentation devices are
    connected.

And the problem is? The DE205 is an ISA card which is much slower than
the builtin PCI Ethernet adapter.  It is expected that one would see
worse performance on the DE205.
