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

[Mika Lehtonen]

Hi Kai,

you haven't been telling us why you want to load your data as an 
OL-layer, what's the format of your data and what is "my server". 
Rendering vector in browser is definetely slow, especially in IE. If you 
just want to publish it, or an image of it, WMS is probably the best 
option. But then you have to have a WMS-server (Mapserver, Geoserver 
etc.). Please, tell us more.
