It is a big red flag to me if a project claims "fast", but does not prominently show benchmarks. Previously I have seen projects that claim to be the fastest which are 10x slower than alternative popular projects.
There are two major benefits I can see from making public benchmarks: 1. showing which other projects you are competing with and 2. having a benchmark suite you keep an eye on helps you actually make your project fast.
