I have built a file upload and display feature that generates a temporary vector layer [as if markers] that are a series of graduated circles with mouseover popups. This works like a treat for relatively small files of points. But if I load a lot of points [over 2,000] it takes a long time to load and panning and zooming is very slow. I assume its just the number of local vectors.
Is there any techniques that I could use to improve load times as well as navigation refreshes? Cheers, Brad..
