Jim Can you tell what speed the OSA ICC card is running? 10 Mbs/100Mbs etc.? eric At 02:47 PM 6/20/2006, you wrote: >I am finding that using the Z890 ICC and either of my tn3270 clients to >connect to our ZVM system is quite a bit slower than using the TN3270 >services provided by the TCPIP virtual machine. > >The two clients I am using are Jolly Giant and Vista. > >I've configured and tested the clients as models 2, 3,4 and 2E, 3E, 4E. > >The results are repeatable.=20 > >The Jolly Giant emulator has an option for host response time. > >When tcpip is providing tn3270 services, the host response time for a >simple logon is about 0.02 seconds.

Z890, ZVM 5.2, and ICC
I am finding that using the Z890 ICC and either of my tn3270 clients to connect to our ZVM system is quite a bit slower than using the TN3270 services provided by the TCPIP virtual machine. The two clients I am using are Jolly Giant and Vista. I've configured and tested the clients as models 2, 3,4 and 2E, 3E, 4E. The results are repeatable. The Jolly Giant emulator has an option for host response time. When tcpip is providing tn3270 services, the host response time for a simple logon is about 0.02 seconds. When the ICC is providing tn3270 services, the host response time is about 1.00 seconds. When using a Model 4E session and scrolling forward/backward on a filelist screen, the tn3270 services host response time is about 0.02 seconds. The ICC host response time is about 1.4 seconds. Are there configuration settings to improve the performance of the ICC or is this just a fact of life?? I am willing to experiment if I knew what knobs to twist.
