[OpenLayers-Users] Performance of own (vector) data in Open Layers

[Kai Behncke]

Dear Lars,

thank you for answering.
With own data I just mean data that lie on my server, it would be nice to implement them "directly" for example as a shape, but I think this is not possible, so as far I can see WFS should be the easiest way (??).

Well, in the moment I have 500 Features via WFS, it takes sometimes more than 2 seconds, what is far to much I think. I will do some checks to find out the bottleneck.

Best regards, Kai
