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
0.94.14 178K 220K
0.96.0 20K 15K
0.96.1 173K 168K
Release 10 YCSB clients (reads/seconds) 25 YCSB clients
0.94.14 50K 52K
0.96.0 23K 23K
0.96.1 52K 54K
