Maintain public benchmarks

There are some well-known public benchmarks comparing Express with other Node.js web servers. However, some implementations of Express used in these benchmarks are outdated — they rely on old versions of Node.js and Express itself, which results in unfairly poor performance outcomes.

I believe the Perf Working Group could help maintain and update these benchmarks to better reflect Express's actual performance and promote more accurate results.

Here are some of the benchmarks I’m referring to:
