I think it shows that the author(s) behind the library is/are committed to improving performance. Sure, a lot of companies like to publish benchmarks like this to make their product look better than it is (E.g. only showing the good parts), but in this case I know the author and I can vouch that he is independent and uncompromising. You could argue that the baseline performance of a library doesn't matter as much once you start adding lots of custom logic on top, but it's still highly relevant for lightweight workloads (which are actually quite common E.g. Basic chat systems).
