I've been working on a TCP session monitor. It reports MB/Second +
changes to the TCP parameters, such as change in window size, buffer size
etc. all of which affect throughput.

Grasping at straws here, IBM support center is baffled too.
To clone z/OS maintenance to various disconnected sysplex’s I do a DFDSS dump,

is some environmental issue causing slow file transfers to some
