swoole websocket 性能问题

### 问题描述

### Swoole版本，PHP版本，以及操作系统版本信息
Swoole 4.45版本这样
php 最新的7.4 以上
系统 centos7  虚拟机 双核四线程 2G内存 磁盘是磁盘阵列RAID0的 2个盘 给他40GB空间

### 相关代码
websocket代码
```php
<?php
class web_socketer{
	private $websocket;
	public function __construct() {
		$this->websocket = new swoole_websocket_server("0.0.0.0", 9501);
		$this->websocket->set([
			'worker_num'      => 2, //开启2个worker进程
			'max_request'     => 4, //每个worker进程 max_request设置为4次
			'task_worker_num' => 4, //开启4个task进程
			'dispatch_mode'   => 4, //数据包分发策略 - IP分配
			'daemonize'       => false, //守护进程(true/false)
		]);
		$this->websocket->on('Start', [$this, 'start']);
		$this->websocket->on('Open', [$this, 'open']);
		$this->websocket->on("Message", [$this, 'message']);
		$this->websocket->on("Close", [$this, 'close']);
		$this->websocket->on("Task", [$this, 'task']);
		$this->websocket->on("Finish", [$this, 'finish']);
		$this->websocket->start();
	}
	public function start($websocket) {
		echo "#### 启动 ####".PHP_EOL;
		echo "SWOOLE 版本".SWOOLE_VERSION . " 服务已启动".PHP_EOL;
		echo "主进程 pid: {$websocket->master_pid}".PHP_EOL;

		switch ($data['type']) {
			case 'login':
				$msg = '我来了...';
				break;
			case 'speak':
				$msg = $data['msg'];
				break;
		}
		//已经连接的 客户
		foreach ($websocket->connections as $fd) {
			$connectionInfo = $websocket->connection_info($fd);
			if ($connectionInfo['websocket_status'] == 3) {
				$websocket->push($fd, $msg); //长度最大不得超过2M
			}
		}
		$websocket->finish($data);
		echo "########".PHP_EOL.PHP_EOL;
	}
	public function message($websocket, $frame) {
		echo "#### onMessage ####".PHP_EOL;
		echo "receive from fd{$frame->fd}:{$frame->data},opcode:{$frame->opcode},fin:{$frame->finish}".PHP_EOL;
		$websocket->task(['type' => 'speak', 'msg' => $frame->data]);
		echo "########".PHP_EOL.PHP_EOL;
	}
	public function finish($websocket,$task_id, $data) {
		echo "#### onFinish ####".PHP_EOL;
		echo "Task {$task_id} 已完成".PHP_EOL;
		echo "########".PHP_EOL.PHP_EOL;
	}
	public function close($websocket, $fd) {
		echo "#### close ####".PHP_EOL;
		echo "client {$fd} closed".PHP_EOL;
		echo "########".PHP_EOL.PHP_EOL;
	}
}

<script>
var  index=0;
if ("WebSocket" in window) {

	var ws = new WebSocket(wsServer);
	ws.onopen = function (evt) {
		if (ws.readyState == 1) {
			console.log('WebSocket 连接成功...');
		} else {
			console.log('WebSocket 连接失败...');
		}
	};
	ws.onmessage = function (evt) {
		console.log('接收到的数据: ' + evt.data+'->当前时间:'+get_time());
	};

ws.onerror = function (evt) {

		console.log(evt);
	};

ws.onclose = function() {

}else {
	alert("您的浏览器不支持 WebSocket!");
}
function send_msg(){
	index+=1;
	for(i=0;i<10000;i++){
		ws.send("你好啊 服务器 当前时间:"+get_time()+'->'+index.toString()+':'+i.toString());
	}
}

function get_time(){
//定义时间变量对象mydate
	var mydate=new Date(); 
	var hour=mydate.getHours();
	var minute=mydate.getMinutes();
	var seconds=mydate.getSeconds();

### 你期待的结果是什么？实际看到的错误信息又是什么？
压测试一段时间后 延迟很大
刚开始 很快就能返回 对应信息
但是 压测一段时候后发现 一个消息返回需要 10秒以上了 swoole 也提示错误了  暂时不清楚咋解决 理论上 应该也不是我解决吧 应该是配置问题
