We are excited to show our Scrolling Performance Enhancements, these enhancements apply to the WPF Pivot Grid. This performance enhancement was accomplished by significantly improving the scrolling algorithms in this release. The result is the scrolling can be up to five times faster in layouts that contain 300 columns, 1200 rows, and 60 data fields. The performance enhancements will very depending on the shape and size of your data but we are confidant you will see the difference.
Below is a comparison time line of scrolling performance in 10.2 vs 11.1.

We hope you will enjoy the new responsiveness this will give the Pivot Grid.
