Hi, just to be sure, you mean more than 1,000 points/markers (not polygons or lines)? In the only experience I had with that many points I wasn't loading the KML through OpenLayers.Layer.Vector (as in http://openlayers.org/dev/examples/kml-layer.html, for example). We had a 'upload' dialog, so that the user could choose a file from his machine. We then used the KML Parser to extract the features and then added to a layer. This way we were able to display around 20,000 markers (before things started to get slow). If what you're doing is something similar I could give you some hints.
