I ran some tests of local filesystem YCSB. I used the 0.90 client for 0.90.6. For the rest of the tests I used 0.92 clients. The results are attached.
0.90 -> 0.94.0RC3 13% faster 0.92 -> 0.94.0RC3 50% faster This seems to be a pretty large performance improvement. I'll run some tests on a cluster later today.
