I have also met this issue. And I fixed this problem just exactly as the author does

The nginx config file is nginx-ori.conf, the content:

thread_pool dlb threads=16 max_queue=65535;
http {
    aio threads=dlb;
    xxx;
}

Start the nginx: nginx -p pwd -c nginx-ori.conf Start the benchmark:

k6 run -u 32 script.js

And the content of the script.js:

import http from 'k6/http';
import { check, sleep } from 'k6';

export let options = {
	insecureSkipTLSVerify: true,
	noConnectionReuse: true,
	noVUConnectionReuse: true,

	duration: '20s',
};

export default function () {
	const res = http.get('https://localhost:9001/', {headers: {"Accept-Encoding": "gzip"}});
	check(res, { 'status was 200': (r) => r.status == 200 });
}
