I think it should be pretty obvious, actually.  Command overhead is large 
(and not getting much smaller), and clustering primarily serves to reduce 
the number of commands and thus the ratio of command time vs. data time.

So unless the clustering implementation is extremely poor, it's 
worthwhile.
