These changes look about right. While you can?t change the speed of light, anything you can do to reduce the amount of traffic will help quite a bit as (except for satellite) volume adds to latency at the low bandwidth bottlenecks (aka ?the local loop?). Reducing encryption might help and certainly won?t hurt performance. That the loop has Asynch speeds does not matter (other than the limits on the bandwidth, eg: 512/1024 will always be better than 512/512). I have seen some site use appliances, such as Packeteer, to help with prioritizing RDP/ICA versus other local loop traffic at the remote ends to help as well. Third party reduced bandwidth printing solutions can help also. Limiting ability to copy files between server and local PC also.

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?

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. > -----Original Message----- > From: thin-bounce@xxxxxxxxxxxxx > [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Foote, Eric > Sent: Monday, 11 October 2004 4:04 a.m. > To: thin@xxxxxxxxxxxxx > Subject: [THIN] Re: Slow performance over WAN > > Don't rule out the VPN either, could be someone is accessing > resources other than Citrix from your LAN which would fill > the pipe pretty quickly. > > Eric > > -----Original Message----- > From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx]On > Behalf Of Rob Beekmans > Sent: Monday, October 11, 2004 6:07 AM > To: thin@xxxxxxxxxxxxx > Subject: [THIN] Re: Slow performance over WAN > > > Nicolai, > > Is their line 1:1 ADSL or more split up....that's what's > bugging connection over here mostly....1:20 line 256K and > they wonder why they have slow connection..... > > I'd check that direction..... > > Met vriendelijke groeten / With kind regards > > Rob Beekmans > Technical Consultant > A-Tree Automatisering > > St. Annastraat 167 / 6524ET Nijmegen > Business Phone: +31 24 6452000 > Business Fax: +31 24 6450463 > Business website: http://www.a-tree.nl > Business E-mail: R.Beekmans@xxxxxxxxx > > Private E-mail: RobBeekmans@xxxxxxxxxxxxx Private E-mail: > rob.beekmans@xxxxxxxxx > > > - Disclaimer - > "De informatie verzonden met dit e-mail bericht en de > bijlagen is uitsluitend bestemd voor de geadresseerde(n). > Gebruik van deze informatie door anderen dan de > geadresseerde(n) is verboden.
