unfortunately not. OpenLayers clusters on client-side. This is fine for 
smaller data sets but not feasible when the amount of data grows.

I had written some tech stuff about server-side clustering, if you are 
interested:

For data like the 170 million edits of our top-user a client-side 
strategy will not work.
