Note: the last group of benchmarks doesn't include HttpRouter, for HttpRouter will panic on those flexible URL patterns.

From the results, we can find that

  • (from the first group of benchmarks), HttpRouter performs best for pure router function. (It is proved that the main reason TinyRouter and ChiRouter look slower than HttpRouter is they both support get path parameters from request context but HttpRouter doesn't defaultly. When all the three packages use request context to return path parameters, their performance differences are smaller than 20%.)
  • (from the middle groups of benchmarks), with more and more workload for a single request, the advantage of HttpRouter becomes smaller and smaller.

Conclusions

  • If your server project needs a high URL pattern flexibility, select any route libraries used in the above benchmarks except HttpRouter.
  • If the average response size is large than 8k bytes, any router libraries used in the above benchmarks are capable.
  • If the average response size is very small and you don't care about the URL pattern flexibility, HttpRouter may be the best choice.]
