These are some microbenchmarks at best. Still nice to know who wins, but not representative of any real work scenario.

They often strip out framework functionality and hyper-optimise for the specific benchmark, including things like pre-allocating the exact amount of memory needed to serve the request, not doing route matching et all, etc.
They are basically an exercise in "how clever can we be to win the benchmark" rather than a realistic portrait of real world performance.
But still, these benchmarks have their uses but there are a lot of caveats you need to consider when looking at the results.
