Benchmark Testing

Benchmark Testing Implementation for Various Node.js Frameworks
This pull request introduces a comprehensive benchmarking test that compares the performance of several popular Node.js frameworks. The benchmarks were designed to measure each framework’s:

Requests per second: The number of requests the framework can handle per second.
Transfer rate: The amount of data transferred per second.
Latency: The average time taken to respond to requests.
Latency Stdev: The standard deviation in the response time across all requests.
Max Latency: The maximum latency observed during the tests.

Frameworks Tested:

uWebSockets.js (uws)
Node.js HTTP (http)
Fastify
Koa
Restify
Hapi
Express

Results Summary:
The table below highlights the key metrics recorded during the benchmarking:

As commented in expressjs/discussions#261 (comment). Maybe we want to expand our tests and compare against releases rather than other frameworks as Fastify already provides great comparison tool: https://fastify.dev/benchmarks/ (https://github.com/fastify/benchmarks/). cc: @expressjs/express-tc

As discussed, we're prioritizing comparisons between different Express releases over benchmarking against other projects. Therefore, I’m closing this issue in reference to expressjs/discussions#261.

But thanks a ton for bringing this up @andrehrferreira 👍

@IamLizu Thank you for your attention =)

While I agree we first and foremost care about comparing to ensure we are improving, it is very helpful to have this kind of information. While I have not had a chance to review this PR, I just want to say that medium term we will care very much about this, so I am not sure if makes sense to close this PR. It is just that we cannot do any of this work right now until we get into v5 and maybe even v6 in the next year.
