Accepted answer

in my experience, when i have a large number of charts or datapoints, i generally turn off animation. animation adds a lot over processing overhead, and without it highcharts generally handles a lot of data very well.

i guess you could try removing the series and adding the new one for each chart at a time, rather than removing all and then adding all. i doublt this will make much different to your page responsiveness though.

  chart: {
      animation: false
  },
  plotoptions: {
        series: {
            animation: false
        }
  },

score:0

while currentchart.series.length > 0
  currentchart.series[0].destroy()
