Revisit: Slow transfer from remote virtual directory -- iis ftp

We've got a high-visibility problem integrating an application into our
enterprise. We've got a Windows Server 2003 SP1 IIS-FTP server set up
with a few virtual directories that point to remote server shares.
Doing PUTs to these directories works as fast as expected (~600kb/s).
Doing GETs from these directories is amazingly slow (~16kb/s).

This behavior can so far only be replicated by a remote mainframe as
the client doing the GET. Internal servers and workstations (Windows)
are good and fast for both PUTs and GETs. However, this remote
mainframe can GET from a non-remote virtual directory on the same
server fast.

So it seems the combination of mainframe and remote virtual directory
causes this problem. Any insight from this knowledgable group?

I am revisiting a topic I found with the same problem. However there
was no solution posted it is too old to reply to.

Ha! I was helping the poster. but unfortunately didn't figure anything.
I would suggest you engage Microsoft support to look into tihs.
