    Thanks for writing! The Boost module deals with the data points, in this case it would rendering the rectangles for the tasks.

    I don’t think enabling Boost for Gantt would make a very big difference. Rendering 1000 rectangles in SVG should’t be a problem in the first place. I suspect the performance bottleneck is something else, like the grid axis or something.

    Can you share a demo of your problematic chart, where we can do some profiling?

    Here's a demo: http://jsfiddle.net/j5quwvz9/

    I'm using navigator and scrollbar to render 100 items (real use case is anywhere from 1,000 to 10,000) and the dragging and scrolling is very bad. I'd be happy to know if there's some way I can make this perform better.
