More info in my post: https://www.outsystems.com/forums/discussion/43341/rendering-chart-with-chart-module-is-very-slow-is-it-possible-to-render-it-on-cl/#Post161637TL;DR:When using the boost mode of Highcharts the rendering of the graph will not use SVG but WebGL. In our testcase there was a significant performance gain.
If the charts module uses Highcharts this can probably be implemented.
