No the transfer rate does not include the login time. The login time is very short. We tried it interactively from tso and the transfer rate is as slow as in batch.

If so, have you tried an interactive ftp to see how long the login is taking? If it is taking a long time, the login time by itself may explain your slow transfer rate, while the transfer itself may be working just as fast as a transfer to Windows. We had slow Linux ftp logins (30 seconds before we even got a prompt for the userid) which turned out to be due to three reasons: the ftp server on Linux was running under xinetd, not as a daemon; xinetd was issuing ident requests (port 113) back to the client machine, due to USERID being specified in /etc/xinetd.conf or the /etc/xinetd.d file for the ftp server; and port 113 traffic was blocked. I won't go into more detail, since I don't know if any of this applies to your situation.

If I do the same FTP transfer to a Windows server I got a transfer rate of about 900K/sec. The mainframe OSA card is running at 100 Mb/sec full. Since the Windows and the LINUX server are on the same switch and got the same throughput capability I suppose that there is an optimal setting that is done automatically when the transfer is done with a Windows server but this setting is not done automatically with a LINUX server. I tried PASV but it didn't change the bad transfer rate. Could you tell me what this setting could be?
