Benchmark performance - Githubissues

Hi! I decided to try out uWebSockets.js

I'm running a simple app, this is the main code


import HyperExpress from 'hyper-express'
import { MongoClient } from 'mongodb'

const webserver = new HyperExpress.Server()
const mongoClient = new MongoClient("mongodb://mongo:mongo@bench_he_db")
mongoClient.connect()
const db = await mongoClient.db('bench')

// Create GET route to serve 'Hello World'
webserver.get('/', async (request, response) => {
    response.send('Hello World');
})
webserver.get('/bench', async (request, response) => {
    const articles = await db.collection('articles')
    let ids = []
    let q = 50
    while (q--) {
        ids.push(parseInt(Math.random() * 100000))
    }
    const data = await articles.find({ n: { $in: ids } }).toArray()
    // console.log(data)
    return response.send(JSON.stringify(data))
    // return response.send(JSON.stringify({a:1}))
})

webserver.listen(8000)
    .then((socket) => {

        console.log('Webserver started on port 8000')
    })
    .catch((error) => console.log('Failed to start webserver on port 8000', error));

basically retrieving 50 random docs from a mongodb database where we have already 100k documents, when i try to benchmark this with ab it hangs, then i tried wrk (using: wrk -t1 -c500 -d10s http://localhost:8000/bench) and it gives me about 350 reqs/s using 100% (12 cores on ubuntu), while the same exact test, on the same machine, using only 15% of the same CPU - gives me about 5600reqs/s on fastify.js

NOTE1: i tried a simple {hello: "World"} without accessing the db and on 25% CPU load uWebSockets gives me about 200000 reqs/s NOTE2: both apps run in docker containers

Can't get if the issue is on the mongo driver side (although i used the same driver for fastify) or on the framework itself, or maybe i did something wrong )?

IF you have any idea, please let me know. Thank you!
