复现代码:

<?php

use Swoole\Runtime;

$server = new Swoole\Http\Server("127.0.0.1", 9501, SWOOLE_PROCESS,SWOOLE_SOCK_TCP);
$server->set([
  	'worker_num'	=>  2
]);
// 不开启协程就无事发生
Runtime::enableCoroutine();

$server->on('request', function ($request, $response) {
    \Seaslog::info('something');
    $response->end("<h1>Hello Swoole. #".rand(1000, 9999)."</h1>");
});

$server->start();

复现方式:
ab -k -n 10000 -c 100 http://127.0.0.1:9501/
