profiling

There is a quite big LOB silverlight application and we wrote a lot of custom controls which are rather heavy in drawing.

All data is loaded by RIA service, processed and bound (using INofityPropertyChanged interface) to the view.

The problem is that first drawing takes a lot time. Following calls to the service (server) and redrawing is quite fast.

I used Equatec profiler to track the problem. I saw that processing takes a couple of miliseconds only so my idea is that the drawing by SL engine is slow.

I'm wondering if it is possible to profile somehow processes inside SL to check which drawing operations are taking too much time. Are there any guidelines how to implement faster drawing of complex custom controls?
