Hi all.
We have realized a test dlsw connection (all via ethernet), between two as400 systems.
We have tried first a file transfer using a back-to-back connection (using a crossover cable), and time to complete copy is 4 minutes.
So we have tried dlsw:
as400_1----r1--------r2-----as400_2
and performance is 4 hours (!!!!!).
We have checked all checkable, duplex mismatch (nothing), cable, ios releases, changed routers, but file transfer is very slow...
We understand that we can't obtain same performance like with a crossover cable, but I think that 4 hours is too much...
Configuration of routers are specular, first is:
service timestamps debug datetime msec
service timestamps log datetime msec
service password-encryption
