System model number 270
2838 Operational Ethernet Port
2744 Operational Token-Ring Port
Release of base option . . . . . . . : V5R2M0 L00
TL03077 Temporarily applied
I too wonder why the system performed so poorly with concurrent use of the
Ethernet and Token Ring adapters. If it helps to identify the problem, the
TR IP address was 10.10.10.1, subnet 255.2555.255.0 and the Ethernet
continues to be 10.10.11.1, subnet 255.255.255.0
Whatever the reason, I have not enabled the Token Ring TCP/IP configuration
again and reconfigured routes to continue processing from the 10.10.10.x
Token Ring devices. I have been trying to eliminate the Token Ring
environment here for years. Because of this latest throughput issue,
management is starting to agree. :)
I guess we should have stayed on twinax until the AS/400 supported
Ethernet. Hindsight = 20/20

Ken,
I know this thread has been beaten to death - I've been away from the list
for a few weeks and am just catching up - but I don't recall seeing
mentioned anywhere details of your system:
- What model/processor feature
- what Ethernet adapter
- what release of OS/400 and cumulative PTF level
I'm still curious why use of both Ethernet & TokenRing adapters together
cause the slow performance on Ethernet.

Re: Why is the iSeries so slow
Sorry you missed my earlier post Jim....
Yes, the FTP problem on our iSeries seems to be resolved. As Marty had
mentioned, he too had throughput problems on an iSeries that contained
both
an Ethernet and Token Ring adapter. His post caused me to disable the
Token
Ring on our system and run exclusively on the Ethernet adapter. Once done
the FTP throughput was more reasonable. Not as fast as other platforms
deliver data but fast enough to make the process acceptable.
Unfortunately, this original post of mine did, in fact, result in an
isolated and unique situation. Thus not really able to help the general
iSeries community.
IMHO, it did however stir up emotions showing some of the same narrow
minded opinions of the midrange community.
