Hi, I had a similar problem. I have over 6000 markers in a page with popups and tried different solutions. Since I wanted a popup for every marker, using WFS was just killing my page. I ended up (with great help from CampToCamp) with a solution of getting the layers as WMS and using a WMS getFeature call on click so that when I click on a marker it queries GeoServer for the features. Of course a small delay sometimes but the speed is quite good overall. I looked into strategy cluster ( http://openlayers.org/dev/examples/strategy-cluster.html) which seems nice but I am a newbie so I did not get it. But it seems like a very good solution. Anyway you can take a look at my page (not finished!) with over 6000 markers (dev server for now) http://naturkart.no/dev/
