Hi everyone,
I need some help understanding how files are transferred in a TS
environment. We have a client that is using our software to open image
files that are stored on a server. There is a very big delay in
opening TIF image files, while all other formats open quickly. File
size is not the problem because the TIFs are smaller than the other
images. If we copy the files to the desktop and open from there, there
is no delay at all.

The client says they have determined that the delay is in the upload
of the file from the local computer to the TS session. I have very
little TS experience. I am not sure I understand what this upload is.
Can someone explain? Does anyone have an idea what might cause the
delay?

Thanks,
Mike

On a file server on the same network as the TS box?

Meaning, the user's *client* machine on the network....not the desktop
folder in their TS session?

What happens if they open the same graphics file in, say, Windows Picture &
Fax viewer, and *not* your software?


I don't see where there's any upload at all. However, if they're indeed
using local drive redirection in their TS session to access their own
workstation's HDs within the session, yeah, that *is* slow...but why would
people be doing this regularly or storing files on their workstations to begin with?

If the TS user is accessing a network drive w/in his or her TS session,
there is no 'upload' to speak of. They're just opening the file accross the
network, same as they'd do from a workstation.

Terminal Services / remote desktop in general does not handle graphics very well, note.
