[OpenLayers-Users] Alternatives to get rid of WFS layers

[Roel De Nijs]

Because our layers represent a sewerage system, which can be quite dense. The number of visible features on a given zoom level can range from 5000 to 25000. We currently use WFS for selecting (and WMS for drawing), but with these kind of numbers the performance of our web application is poor, very poor. That's why we are on the lookout for any alternatives/workarounds.

So a user could select some features (using mouse clicks and/or box selection). Then these selected features could be used to execute another function in the application. But now these WFS layers don't exist anymore, so wondering what's the best approach to simulate this behavior.

Why not use WFS as well? I use WFS for selecting, WMS for drawing. If you are using Geoserver backend, you have WMS and WFS available for every layer.
