Hi,
We appreciate you reaching out to us with your inquiry.
There is a boost module, it works for Highcharts and Highstock only. Unfortunately, the Highcharts boost module does not support Highmaps. The boost module is a “renderer-in-a-module”. Including modules/boost.js will, by default, activate boost for all series that support it (line series, column, bar, treemap, heatmap, scatter, bubble, area):
