Hi everyone, this is the first post on this forum. I have search the problem on the forum, but find no anwser. What I need to solve is: I have more than 400 points need to show on the map, these points query my db every 10 secs, and change their color according to the return value. I use the openlayers.layer.marker to implement, but in ie the markers make the map so slow when zooming. Then I move to openlayers.layer.vector, but it's even slower than marker. Any suggestion in such "Adding large and dynamically changed markers" situation? -- View this message in context: http://n2.nabble.com/How-to-add-many%28%3E400%29-markers-to-the-map--tp2631715p2631715.html Sent from the OpenLayers Users mailing list archive at Nabble.com.
