Setup is as follows.
HP C3000 blade enclosure with 4xHP BLC460 Blades, dual quad core cpu, 4gb RAM.
Server 2003 R2 with Presentation 4.5 advanced, HRP 3.
6 Branch offices connected via leased line MPLS in a combination of 1mb and 2mb bandwidth. 8mb fibe at head end of the mpls.
Citirx using published apps, including Office 2007, I.E7 and a couple of Accounts apps fairly light weight. All speed screen and latency reduction configured.
Printing through session based printers from a print server at head end and then down to the IP of the printer.
The setup serves around 100 concurent users at any one time from the branches. Head end does not use Citrix but in a test enviroment performance is 100% perfect.
We have requested QoS to be enabled on the MPLS for Citrix priority, however in the mean time.... We get random sticky sessions and lag when typing, does any one have any pointers?
