Then again, MemSQL didn't design the benchmark. They beat Oracle at their own benchmark on massively cheaper nodes.

I think the LMDB team has done a really good job with this type of comparative benchmark. They took the LevelDB benches, then ran them against a lot of competitive products, both new and legacy, and gave a really good view of the entire field, in terms of performance on a number of dimensions:
