Does Load Runner actually performance test the client piece on a client-server application? Or does it just do requests from the client?

I have a web app that has an active x control on it, would load runner be able to performance test this piece?

How is the citrix functionality?

I also have a web page that runs on citrix. There is a lot of client side scripting that is executed. This causes major bottlenecks on citrix.

Would Load-Runner be able to do this type of testing, or is it just going to give me the performance on the web server?

I need the performance of the client piece on citrix.

Thanks to anybody who replies.
