Performance coding against TFS

Question

Hi, 

I am working on an application that provides an UI of some of the TFS Data. When retrieving data from TFS I find it very timeconsuming. 

We have profiled the performance using af ANTS Performance Profiler 4.0, and found the following measures:

TFSServerObject.GetService(typeof(WorkItemStore))        :  7600 ms

For fetching the workitems I use the WorkItemStore.Query(...) Methods. and this works fine.

I'm using the WorkItemFormControl provided by the TFS, and whenever I set the WorkItem  property on the WorkItemFormControl, it uses about 4300 ms to render it self.

I would of course like to speed up the application.

Do any of you guys have any tips, tricks, best practices that could help me tune up my application performance?

Best Regards
