Slow zooming animation when loading a large route (~50000 coordinates)

[gaetano603]

I loaded a route on the map which is made up of about 50,000 coordinates (latitude and longitude). The zoom function on the map is very slow. Adding preferCanvas: true to the map options resulted in a clear speed improvement but not enough with that many coordinates. Is there a way to increase its speed?

I solved deleting these settings from options.

distanceMarkers: true,
distanceMarkers_options: {
  lazy: true
}

Hi @gaetano603, thanks for the report (and workaround).

Please can you send two links to two different demos showing the difference in performance between this options turned on and off?

As i remember, the distance markers should also support the canvas renderer:
