🐛 Bug Report

I reran the benchmarks, my results are way lower than yours.

To Reproduce

Rerun the benchmarks, with the following bugfix:

-router.on(['GET', 'POST', 'PUT', 'PATCH', 'OPTIONS', 'DELETE'], '/service/*', (req, res) => {
+router.get('/service/*', (req, res) => {

wrk -t8 -c50 -d20s http://127.0.0.1:8080/service/hi

Expected behavior

Somewhat similar benchmarks.

My benchmarks:

fast-proxy-undici/0http: Requests/sec 10259.59 (HTTP pipelining = 10)
fast-proxy/0http: Requests/sec 6773.80
fast-proxy/restana: Requests/sec 6460.21
fast-proxy-undici/0http: Requests/sec 9448.67 (HTTP pipelining = 1)
fastify-reply-from: Requests/sec 5635.55
http-proxy: Requests/sec 3105.40

As you can see I'm getting max 3.3x performance gain instead of your 46.6x.
Without the above mentioned bugfix, the first test clocks in at 39305.96 Requests/sec (12x faster than http-proxy). Even then it is WAY slower compared to your benchmarks.

I don't know what is exactly going on, but I think it's fair to say that your benchmarks are wrong and misleading.
