webman 用云数据库 并上去了 所有进程都busy

webman用云数据库经过一轮并发强度1500后所有进程处于busy状态并且恢复的很慢用.本地数据库就好点能到cpu差不多打满

服务器 ：12核心 12g内存 10m 带宽
测试用例 ： 一个简单的sql 查询

云数据库配置:serveless
数据库类型 MySQL5.7
数据库内存 [1024 M - 16384 M]
CPU [0.5 - 8]

程序代码 (此代码和我thinkphpfpm 线上真实代码一致)

<?php
namespace app\controller;

use support\Request;
use support\think\Db;
use support\Response;
class UserController
{
    public function hello(Request $request) : Response
    {
        $param = $request -> get();

        $lon = $param['longitude'];
        $lat = $param['latitude'];
        // var_dump($param);
        #更新位置
        // RealAddressService::real_address($lat , $lon);

        $keyword = $param['content'];
        if($param['sort'] == 1){
            $sort = 'dist asc';
        }
        if($param['sort'] == 2){
            $sort = 'fo.order desc';
        }
        if($param['sort'] == 3){
            $sort = 'sort asc';
        }

报错信息

这里粘贴报错

webman 配置截图

php8.2
wenbman 2.1
event 扩展已安装
linux 优化已做

单请求耗时

并发1500 进程全busy 并且 恢复很慢

我用thinkphp fpm 同样的 强度模拟 好无压力 cpu 最高只占到 40 ，但是 fpm 单请求有180ms
