Hi, Ted

Do you have the slides?
I don't have the full slides.  The image was passed to me by a co-worker in
China.  We are evaluating it.
I am copying the numbers below:

Release        3 YCSB clients (puts/seconds)             5 YCSB clients
(puts/seconds)
0.94.14         178K                                                  220K
0.96.0           20K                                                   15K
0.96.1           173K                                                  168K

Release        10 YCSB clients (reads/seconds)         25 YCSB clients
(reads/seconds)
0.94.14         50K                                                    52K
0.96.0           23K                                                   23K
0.96.1           52K                                                   54K
