Hi Brad, You are right, it is because the number of features is too important ( see the faq in the section vector <http://faq.openlayers.org/vector-related-questions/what-is-the-maximum-number-of-coordinates-features-i-can-draw-with-a-vector-layer/>). One solution is to use the cluster strategy, it will speed up your display (see the two examples: http://openlayers.org/dev/examples/ ) If you don't want to cluster your features, another solution would be to use a simple wms for big extents and then use your vector layer with a BBOX strategy for smaller extent. That way only the features in the visible extent will be requested (see also the example). That all I came up with, maybe someone will have a better idea...
