使用workerman测试gateawayworker连接过慢

使用的是官方的demo

客户端代码

require __DIR__ . '/workerman/Autoloader.php';
use Workerman\Worker;
use Workerman\Lib\Timer;
use Workerman\Connection\AsyncTcpConnection;
$worker = new Worker();
$worker->onWorkerStart = 'connect';
function connect(){
    static $count = 0;
    // 2000个链接
    if ($count++ >= 10000) return;
    // 建立异步链接
    $con = new AsyncTcpConnection('ws://127.0.0.1:3458');
    $con->onConnect = function($con) {
        // 递归调用connect
        connect();
    };
    $con->onMessage = function($con, $msg) {
        //echo "recv $msg\n";
    };
    $con->onClose = function($con) {
        echo "con close\n";
    };
    // 当前链接每10秒发个心跳包
    Timer::add(10, function()use($con){
        $con->send("ping");
    });
    $con->connect();
    echo $count, " connections complete\n";
}
Worker::runAll();

服务端代码

  public static function onConnect($client_id)
    {
        // 向当前client_id发送数据 
        Gateway::sendToClient($client_id, "Hello $client_id\r\n");
        // 向所有人发送
        Gateway::sendToAll("$client_id login\r\n");
    }

   /**
    * 当客户端发来消息时触发
    * @param int $client_id 连接id
    * @param mixed $message 具体消息
    */
   public static function onMessage($client_id, $message)
   {
        // 向所有人发送 
    //    Gateway::sendToAll("$client_id said $message\r\n");
   }

服务器8核
客户端与服务器在同一台服务器上 本机访问
gateaway进程8个 business24个
cpu占用一半 内存几乎没用
event内核已安装 linux内核已优化
onMessage里的广播没屏蔽前跑到两千多就卡了，屏蔽后1w连接需要6，7分钟才能完成
想请教下是原本就是这样还是我linux优化不到位
