Dear Mika, well "my server " is a normal root server in the Internet. "My data" in that case are Vector-Point-Data, I have them in a PostGIS-Database or can have them as a "typical" shape-file. I`m quite new to Open Layers and definetely quite impressed.
I wonder in general now which way might be the most performant way to show "own" geodata (in Combination with the google-api-layer,osm-api-ayer,virtual earth-api-layer) to the public in Open Layers. But, well, I will test beside from that question also how to improve the speed of the WFS, I`m pretty sure there will be some possibilities (indizes and so on).
