Ok - so I guess that between 1400 and 3500 inserts per second is reasonably
good results -- we are going to continue working on our custom code but it
seems like we need a design that uses lots of row-keys and fewer column
family keys and is heavily threaded.

Thanks for your help in pointing out this utility/test harness.
