[THIN] Re: Network Optmization : Output queue length very high

Hi,

If it was a global (ie allusers) problem, I'd probably be spending a bit
more time trying to get some useful data out of the NICs. 

As is, my advice, for what it's worth, is forget about the output queue
length because it sounds awfully much like an artefact.

Try disabling the shared clipboard and enabling keyboard/mouse queueing
(on the ICA client). I've also seen some bizarre client performance
issues when a too aggressive virus checker on the client was hammering
the bitmap cache.

Regards,

Rick

If its easy to do, try a different NIC in one of the MF servers and see
if that helps, people have had various problems with broadcom nics (I
assume you're using Dells??). But have a look at the following first-

As for the stuttering, what happens if you're on the LAN with the
servers, do you get this? If not, I'd suggest looking hard at bandwidth
usage on your external connections, they may be very well saturated.
(Also check ping times over them!)

The frozen sessions I'd hazard a guess at being sort of the same thing,
but more extreme. Does the session show as Active or Disconnected when
they report this? You might find setting up the whole Keep Alive keys
thing will help this a little - they will be disconnected rather than
frozen!

There may or may not be something deeper going on, in which case someone
else may well provide more of an insight, but the above is what I'd look
at!
