The SMW store now supports a method getSemanticData() (see SMW_Store.php for docu) that fetches all semantic data for some subject at once, possibly using filters for further performance gain. That should be much faster than the current singular requests used in Special:Browse and hence the new method should be employed now.
The new storage implementation prefetches and caches results, so this is no longer a real issue there.
