The performance of swoole is higher than that of golang?

Code of swoole 

<?php
$http = new swoole_http_server("127.0.0.1", 9501);

$http->on("start", function ($server) {
    echo "Swoole http server is started at http://127.0.0.1:9501\n";
});

$http->on("request", function ($request, $response) {
    $response->header("Content-Type", "text/plain");
    $response->end("Hello World\n");
});

$http->start();

Code of golang 

package main
import (
    "io"
    "net/http"
)
func main() {
    http.HandleFunc("/", handle)
    http.ListenAndServe("0.0.0.0:10056", nil)
}
func handle(rw http.ResponseWriter, r *http.Request) {
    rw.Header().Set("Content-Type", "text/html")
    io.WriteString(rw, "<h3>http server</h3>")
}

are all tested on my machine

Golang swoole

swoole runs in cooperation, go runs in series, are you embarrassed?

https://wiki.swoole.com/wiki/.

IO Model
go language uses single-threaded eventloop to handle IO events, multithreading implements cooperative scheduling, executes user-level code
swoole uses multithreaded eventloop to handle IO events, and multi-process executes user-level php code
Go is single-threaded to handle IO events and cannot utilize multiple cores, and its throughput is slightly weaker than swoole
in actual TCP/UDP dense IO stress tests, swoole performs better than go

copy and paste is a bit watery.
this is determined by language characteristics. We can't evaluate whether the performance is good or not. Each has its own advantages.

look at the version. Forget what the article saw. High concurrency under go 1.9 will cause lock contention, and the scope of locks is too large. Subsequent versions refine the scope of locks

this kind of test is unscientific. This is not called performance testing.
your handler only has a simple output page, and there is no actual processing logic. Try the same complex computing logic. Db operation, which one is faster?
this test can only show that go is not as good as swoole on I answer O scheduling

Swoole is a multithreaded event polling IO. Golang is a thread event polling. In theory, Swoole can accept more connections at the same time.

however, Swoole is the PHP code that executes, executes user code through the Worker process, executes asynchronous logic through the Task process, and communicates through pipes or message queues.

in fact, the execution efficiency is much lower than that of golang. Especially a lot of unoptimized PHP code. Coupled with the fact that interprocess communication is not necessarily faster than locked channel.
