Hi! My customer has a Citrix Farm (6 servers) presentation server 4.5 rollup 1 When the desktop is published and i launch a planning program the prgram ==> 4 seconds to display the planning when i launch via PN 9.x ou PN 11.x the planning publish application ==> 16 seconds to display the planning if I not set "seamless mode" the planning application ==> 4 seconds to display the planning but when the "seamless mode" is off the "session sharing" don't works and if i launch a second application, it runs to the second server (script, profile, create printers) some time... is there a solution to launch the planning application in seamless mode with the speed of the semless mode =off the problem is the same with the rollup 3 for Presentation Server 4.5 Have you some ideas ??? PS : for the test 1 server with only 1 user (the user in same LAN server 100/1000 Mbps) publish desktop launch application 4 seconds CPU 14 /20 % publish planning application ==> 16 - 18 seconds CPU 4 / 5% if seamless mode is off ==> the speed of publish planning isthe same publish desktop Thanks
