WinForms and WPF Charting - Performance Enhancements (Coming soon in v17.1)

One of our primary goals in 2017 is to improve performance across our entire product line. This concerted R&D effort has already paid dividends for a number of key products including our WinForms Chart and WPF Chart controls...

As you'll discover once you start using v17.1, we've fundamentally improved the way in which our .NET Chart controls executes in bound mode. From optimized series data binding to improved multi-pane chart rendering and real-time execution, our internal tests demonstrate that performance when using DevExpress Charts in bound mode is now on par with Charts generated in unbound mode.

Before I get to the metrics, I do want to explain that our job is not finished - we are hard at work on a number of other optimizations and expect to make those available in our v17.2 release cycle. This same commitment to performance excellence is being applied across other DevExpress products, including our Pivot Grid and Scheduler component libraries.

With that, the following table should help illustrate the substantial perf improvements we've made to both our WinForms and WPF Charts Controls....
