[OpenLayers-Users] How can I speed up OL features rendering with SVG2?

If your use case is such that you're only showing a small subset of 
points in the viewport, maybe OpenLayers.Strategy.BBOX strategy would help?

It detects when your map's extent has changed, and re-requests the 
features. If your server-side program can send only features within the 
stated bbox, and the download time is faster than the redrawing time, 
this may be what you want.
