IRTs (Intermediate Render Targets) are used during composition of the final image in WPF. The Perforator tool in the WPF Performance suite also showed a spike in the “Hardware IRT” graph every time the toolbars were refreshed. Often you can create the drop shadow effect a different way – for example, by surrounding the perimeter of the element with shapes filled with gradient brushes, varying the brush opacity to create a soft shadow effect. The conclusion is that bitmap effects such as DropShadowEffect, should be used very sparingly and only on simple elements.
Of course, once we discovered this, we removed the drop-shadow effect and performance was back to normal. Even blinking the caret caused the entire region to be ‘dirtied’. From then on, any time you typed in the text editor, or moved the cursor around, the entire document well would be redrawn. At one point during development, we tried placing a drop-shadow on the document well container in Visual Studio without realizing the performance implications. For example, adding a drop-shadow to a toolbar causes the entire toolbar to be re-rendered whenever one of its buttons changes. The Perforator tool in the WPF Performance suite contains a “dirty region” overlay which helped us track down a performance problem with using drop-shadows in Visual Studio.Īdding a drop-shadow to an element causes the entire element to be ‘dirtied’ even when only a small part of the element is updated. The following tips are based on real WPF performance problems that we encountered during Visual Studio 2010 development. Tipsįor general WPF performance, please start with these MSDN topics:

Whether your performance problem is CPU, disk, memory or network (or a combination), there’s no hiding from this tool.Īlso included in the Windows Performance Toolkit is the WPF Performance suite: This utility includes a “Visual Profiler” giving you a detailed insight into the behavior of your WPF application. Actually, if I had to choose one tool to do performance analysis, this would be it. The profiler team has its own blog: įor a deeper analysis of events and timing at the operating system level, we use xperf from the Windows Performance Analysis Tools: (Download the latest Windows SDK and find the “Install Windows Performance Toolkit” link). This feature is built into Visual Studio itself, so it’s great that it’s always handy. To measure performance in Visual Studio, we used the following tools: Performance optimization begins with measurement and tuning of WPF in Visual Studio is no exception.

The first post in the series covered the motivation for selecting WPF and some of the new WPF 4 features of which Visual Studio takes advantage. This post, the second in a series of articles on Visual Studio 2010’s use of WPF, covers tips and techniques for optimizing performance of WPF applications, and also several areas where we needed to tune Visual Studio 2010 in order to squeeze the best out of WPF.
