When I ping a computer over the WAN link I have about 50 ms.

Just curious but what are your ping times?

What sort of VPN are they using? Is it 3DES? You will find that the
encryption in the tunnel is quite an overhead and significaltly slows down
the ICA traffic. Well, that's the perception anyway.
My advice would be to use a CSG server instead of VPN. CSG is also more
versatile.
But if you want to stick with VPN, make sure you are using the latest
client.
Kind regards,
Jeremy

Please respond to
thin
I took a look at the performance counters and could see that the problem
most certainly is latency if I compare the figures with other users.
I have done the following to reduce the problem:
Server settings:
Reduced screen colors to 256.
Changed encryption from 40 to Basic
ICA Client settings:
Use data compression
Use disk cache for bitmaps
SpeedScreen Latency Reduction ON
I'm not completely sure that everyone of these steps is nessecary? Is
there
something else I could check?

And don't forget latency. They can have all the bandwidth in the world,
but
if there's a high level of latency, their session performance will be
poor.
There are performance monitor counters for session latency under the 'ICA
Session' object on your Citrix servers. You could look at those to see
average latency for the problem clients.
