Hallo Forumers, we have througput bottlenacks in our TSM environment, here
is our configuration:

TSM Server 4.1.4 on OS/390 2.9 with a dedicated TCPIP Stack serving an
OSA-Express Gigabit Adapter (one port) running in QDIO mode  
TSM Clients SUN Solaris as well as HP/UX 4.2

The Network is a dedicated Extreme Gigabit switch with no routing functions,
means we are testing point to point.

with TSM we reach troughputs of max. 15 GB/sec (GigaBytes) which equals 120
Gb/sec. (Gigabits)

On the other hand we have measured throughputs of 35 GB/s using the Software
Chariot from NetIQ.

Is there anybody in the forum with an idea on this throughput problems ? any
help is welcome
