V6多线程压测性能不理想

LIngMax commented 3 months ago


   // $server = new Swoole\WebSocket\Server('0.0.0.0', 4455,SWOOLE_PROCESS);
  $server = new Swoole\WebSocket\Server("0.0.0.0",4455,SWOOLE_THREAD );

  'worker_num'            => 1,#CPU核数的1-4倍 默认值：CPU 核数 Swoole 6多线程版本
  $t=$xi =0;

  $server->on('request', function ($request, $response){

        global $t, $xi,$server;
        $xi++;
        if($xi%10000==0){
            $t1 =microtime(true);
            $m = $t1-$t+0.01;
            echo "进程id   push:".$xi." 秒:".$m."  平均速率:".round($xi/$m,2)." \n";
            $t = $t1;
            $xi = 0;
        }
        @$response->end("啊哈哈哈哈");return;

  });

压测

ab -n 40000 -c 200 "http://127.0.0.1:4455/"

SWOOLE_PROCESS 同样配置达到3w QPS

SWOOLE_THREAD 8k QPS

差了接近4倍

增加worker_num 数量也是同样结果

怎么调整参数也是差不多有什么好的优化建议吗

未发生性能问题。

测试代码


$server = new Swoole\Http\Server("0.0.0.0", 4455, SWOOLE_BASE);

$server->set([
    'worker_num' => 4, #CPU核数的1-4倍 默认值：CPU 核数 Swoole 6多线程版本
]);

$t = $xi = 0;

$server->on('request', function ($request, $response) {
    global $t, $xi, $server;
    $xi++;
    if ($xi % 10000 == 0) {
        $t1 = microtime(true);
        $m = $t1 - $t + 0.01;
        echo "进程id =" . $server->getWorkerId() . "   push:" . $xi . " 秒:" . $m . "  平均速率:" . round($xi / $m, 2) . " \n";
        $t = $t1;
        $xi = 0;
    }
    $response->end("啊哈哈哈哈");
});

$server->start();

检查你的代码，如果是大量使用了线程资源，造成了严重的争抢，确实会导致性能下降。

我用你上面的代码重新测了一下华为云 4核

SWOOLE_BASE 31878.96 [#/sec] (mean)

SWOOLE_THREAD 13263.89 [#/sec] (mean)

接近3倍差距测试结果
