Hi, It sounds a little bit strange, since I did something very similar without having performance problem: http://dev.geoext.org/sandbox/cmoullet/ux/RoutingPanel/examples/RoutingPanelExample.html You can have a look here to see the code that draws the route in OL: https://trac.geoext.org/browser/sandbox/cmoullet/ux/RoutingPanel/ux/widgets/RoutingPanel.js#L623 <https://trac.geoext.org/browser/sandbox/cmoullet/ux/RoutingPanel/ux/widgets/RoutingPanel.js#L623>Hope this helps, Cédric
