Basic advise then is to use Speedscreen Latency Reduction?
It is a WAN situation(some users connecting from one country to another and in
some cases across the Atlantic I believe) and tho I have not been on site yet
what I hear is that when packet states have been analyzed there is a large
queueing up of ICA traffic(which is probably the only real traffic passing).

Also use the SMC Console http://www.citrix4ge.de/ctxsdk/smcc.htm. It will
present you with the latency that each session is experiencing. Very important
information to understand. A Packeteer cannot really adddress WAN
"oversubscription" issues. Force speedscreen latency reduction to on, on the
clients. The initial ICA communications between the client and server negotiate
the best settings. This is not renegotiated during the session.
So if you are using a WAN technology that is not consistent, such as ADSL, it's
very difficult to manage.
Cheers.

Here is Cisco's article on autonegotiation and duplex speeds...
http://www.cisco.com/en/US/tech/tk389/tk214/technologies_tech_note09186a0080094781.shtml
It is very common to see switches set at Half duplex and server cards set at
full duplex or visa versa and this creates a big bottleneck.

If anything the packetshaper should improve the performance not hinder it.
If it is network issues I would start looking at portfast settings if cisco
switches..
http://www.cisco.com/warp/public/473/12.html And also make sure that duplex
speeds are properly configured on the server network cards and switches.
Also check out Michaels article on performance issues where he touches on the
Maxworkitems registry keys..

Will be troubleshooting a situation at a company where Packetshaper is used
including Citrix traffic. Any heads up about the use of Packetshaper and
Citrix. Apparently they are having some performance issues.
