We have seem some lousy FTP performance too. I had a PMR open, but no time to work on it so it got closed.
There is a slowness associated with multiple outbound FTP interfaces and equalcostmultipath. I did receive new module for that. But my old 9672 system, with a single OSA FDDI card was much faster than a new z990 system with 4 OSA GbE interfaces. I don't think it's the GbE though - z/OS here with same network configuration can get 12,000K - 23,000K per second. They have more engines, but still... Open a PMR - I still think there's something not right. Just wish I had more time to work on that. Glenn S. in Level 2 will be familiar with my PMR.

When testing an FTP put from VM to a local FTP server, it appears that I get two to three times better performance when I use the OSA-E FE than the GbE. Both OSAs are connected to the same physical switch. I have looked at the port statistics on the switch and don't see any errors or anything else odd. I don't expect to get better performance out of the GbE port with this test (since the FTP server is on a Fast Ethernet port) but I would at least expect similar numbers. Thanks in advance. Aria.
