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.

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!
