These were timed using binary transfer of SAVFs, so no translation was
occurring in either direction.

Sounds plausible.  I don't have the docs on these PCI adapters, so
I'll look on IBM's website for limitations.

And in fact, it got downright slow!  Zero bytes per second to be
exact...

Well they certainly made my download speeds (400 to PC) more than
double (close to triple), and improved the upload speed as well.
Maybe the PC T/R card can handle 16K receive packets but not 16K send
packets??
