Leo, Also, check your MTU throughout your network. Go with the lowest common denominator to prevent fragmentation. We ended up replacing a ethernet card on one occasion to fix a performance problem. No high level messages at all, just bad performance. Took several comm traces to iron it out. Early versions of ethernet cards on 6xx models need the IBM supplied pigtail removed. Check with your CE. I didn't believe it till I saw the impact. Alex I wouldn't be too ready to blame this on the AS/400 FTP support. We do FTPs between CISC (V3R2, D20) and RISC quite frequently. And the save files are a *lot* bigger. I don't ever recall getting this poor through-put. It is true that FTP and TCP services on the CISC boxes are implemented "above the OS", and IBM improved both protocol and server performance in RISC, but you shouldn't be seeing this type of performance. Some things to look at: 1. Are you running the FTP transfer in batch? If so, what priority does it have? How much pool memory, etc.? If it is running in batch and other applications are running at a higher priority you will see degraded performance. 2. What do you have defined for the frame size on the Ethernet line? Very small frame sizes can degrade FTP performance.
