- My AS/400 installation is transitioning from SDLC and 5394s to TCPIP and
- IBM's AIX-based 5250 emulator. And I am trying to figure out
- the CPU utilization effect of AS/400 TCPIP on my B60.
-
- It appears that AS/400 TCPIP consists of a subsystem QTCPIP and
- some batch server jobs QTCPIP, QTCPTIMER, and some FTP servers. Using
- some Performance Tools collected data it appears that the sum CPU seconds
- of the TCPIP batch jobs is significantly less that the sum of the
- HDLC CPU seconds (today I have up to 30 tn5250 sessions and about 130
- display sessions SDLC attached through multi-dropped 5394-like controllers).
-
- Is it possible that tn5250 sessions do not consume prodigious amounts
- of CPU compared to remote workstation attached displays?
