[THIN] Re: Packetshaper and Citrix

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..
