When BARR/NJE communicates with the host through the Microsoft SNA gateway, BARR/NJE performance can be affected. Communications performance is affected by the communications path between the Microsoft SNA gateway and the network-attached Microsoft LUA client BARR/SPOOL workstation. The link is conducted over the existing Microsoft networking protocols (TCP/IP, NetBEUI, IPX/SPX, or MSDLC).
To reduce overhead and improve performance, a network engineer must verify that no extraneous protocols are loaded on the BARR/SPOOL workstation and that the network environment has been optimized for the desired Microsoft networking protocols.
Communications performance optimization for BARR/NJE through the Microsoft SNA gateway also depends heavily on the link service between the mainframe and the SNA gateway. You can optimize the Microsoft SNA gateway for your particular link service.
