We have had several customers report this issue. Please check the level of
the bos.net.tcp.client for you AIX server. If the reported level for this
component is at 5.1.0.37, call the support center and apply the fix for
APAR IY36925. I have included the problem description for this APAR below:

****************************************************************
* PROBLEM DESCRIPTION:
* Poor TCP/IP performance running applications that do large
* amounts of data transfers. Problems have been seen using
* Tivoli Storage Managers (TSM) and Veritas, but would not be
* restricted to these applications.

Has anyone out there had any kind of FTP/TSM speed problems and what have
they done to fix them.  We seem to be getting 1-2 GB an hour speed on 100
MB Ethernet cards, even with RESOURCEUTILIZATION 5.  The server is an AIX
SP-node at 5.1.0.5, and the Linux86 clients are from 4.2.0 to 5.1.5.0.
Seems to not depend on Version.
