Our IT dept are about to deploy virtualized apps using Citrix XenApp.

One of these apps will be Dynamics AX 4.0 SP2, a ERP client (which I develop on).

They have supposedly reached a roadblock because an external 'Dynamics AX Consultant' has told our IT Dept that Dynamics 4 will not work optimally on Citrix and will run very slow because it is not optimized for Citrix. We have it running in a Test environment now and seems ok. They have been told that the only 'solution' is to upgrade to Dynamics AX 2009 where supposedly this problem as been fixed. (not a small task for my team!)

When I heard about this, I was quite surprised. From my brief knowledge of Citrix, I thought it would be application independent.

How does the citrix app virtualization work, in that a particular app would work better than others on citrix?

Would the speed of the virtualized app not just depend on the resources/network connection the citrix server has?

FYI, Dynamics AX is a 3-tier client/server system, so the client will be accessing a AOS application server, which then accesses the database.

Please enlighten me :)
