[Beowulf] OT, X11 editor which works well for very remote systems?

[John Hearns]

As I am on the subject, it can be hard to assess exactly what the problem
is with remote graphics.
Remember that a squeaky wheel gets more attention.

I was involved with one link to a site in Europe which was using CAD
remotely. I really was never sure whether or not the users
were just unhappy that they had to work in a different way, or that they
were really frustrated by the latency they experienced.
A good solution would have been to have my fly out and sit beside the
users, but this was not on the cards.
I did have several sessions on the phone, watching bandwidth usage and
counters as the users rotated their models.

One telling story is that I did one day get reports of the remote access
being almost unuseable. A lot of flood pings and traceroutes later I proved
that the network link was dropping a huge percentageof packets and the
network provider switches the circuit over...

There are such things as WAN emulators, which introduce delay and packet
loss into links. If I was to do work like this again I would set up a
WAN emulator in the lab first and see what the quality of the experience is
before installing a solution at the remote end.
Time spent here will be well repaid
