How to leave a system in high performance?

Follow a pattern of MVVM projects?

I have the following XAML, but when I run it hangs at the time of passing the focus to other textBox . Why?

My system gets very slow, I do not understand why.

The question is somewhat broad, does not have a specific problem but I will try to help, even in a generic way.

WPF actually has a lot of details that if not observed will generate performance problems. The mechanism is complex and it is not easy to understand all the implications. In addition, defaults are not ideas to generate good performance.

I do not have specific knowledge but there is a lot of material on the subject. I'll list a few. You'll need to read all of them, look for new sources, study the subject a lot, and profile enough to get a good result.

The first thing you need to know is the Performance Analysis Tool WPF . Another tool .

This article starts giving a good explanation of the problem.

Here are tips to improve performance.

Another interesting article a>.

The fact of using the MVVM does not help anything, it can even get in the way in some cases, but nothing significant. Of course, if you use a bad pattern or do it with no pattern at all, it can get in the way.
