There are a bunch of comments related to performance data - the code is available so nothing is stopping anyone from making an unbiased comparison. :)

That said, I intend to publish some sort of performance comparison code / results. The downside with me doing it is that: 1) I know the sparkey code much better than I know level-db or any other solution, so the tuning parameters will probably be suboptimal for the other solutions. 2) I will only focus on our specific usecase (write large bulks, do lots of random reads), which may seem a bit unfair to the most general solutions.
