That doesn't mean a whole lot. Back in the early '00s, ATI and Nvidia were caught optimizing for certain benchmarks that were commonly used to compare video card performance (IIRC one of them was caught with code that specifically cut corners if it detected being run by the benchmark program).
I'm not saying MemSQL is doing anything nefarious, but the fact that the benchmark tests are controlled by someone else doesn't carry a lot of weight.
