Is this slow WPF TextBlock performance expected?

Question

I am doing some benchmarking to determine if I can use WPF for a new product. However, early performance results are disappointing. I made a quick app that uses data bindi

There is a lot one can do wrong in WPF, as far as performance is concerned. Lot of people approach it like a win forms application, html web page, or some hybrid attack on developing the application and because of this there are a lot of bad evaluations of WPF.

I understand that you are trying to do performance testing to see if a WPF can work for your platform and a good example of how to get your WPF application control to perform for the type of load you are expecting can be found at the below link.

Petzold guides you through the process of optimizing an items control to render optimally for the load of data being displayed on the UI.

To do a fair test I would write a sample application that deals with a sample of the data you are going to be dealing with, and then test the performance of that code. There are a large number of optimizations that can be applied to make a WPF application scream and use less CPU, but they all depend on your application and how it is representing your data.

Hope this helps.
