关于自定义进程执行异步任务的问题

代码如下：

控制器

app/controller/Index.php

<?php
namespace app\controller;

use support\Log;
use support\Request;
use Workerman\Connection\AsyncTcpConnection;

class Index
{
    public function index(Request $request)
    {
        $task = new AsyncTcpConnection('text://127.0.0.1:8889');
        for ($i = 1; $i <= 10; $i++) {
            $urlBase = 'http://127.0.0.1:8787/index/sleep?id=';
            $task->send(json_encode(['cmd' => 'get', 'data' => ['url' => $urlBase . $i]]));
            $task->onMessage = function (AsyncTcpConnection $connection, $result) use ($task) {
                Log::info('result:' . $result);
            };
            $task->connect();
        }

        return response('ok');
    }

    public function sleep(Request $request)
    {
        sleep(1);
        return response('sleep 1, id:' . $request->input('id'));
    }
}

自定义进程

app/process/AsyncTask.php

<?php
namespace process;

use GuzzleHttp\Client;
use Workerman\Connection\TcpConnection;

class AsyncTask
{
    public function onConnect(TcpConnection $connection)
    {
//        var_dump(__METHOD__);
    }

    public function onMessage(TcpConnection $connection, $data)
    {
//        var_dump(__METHOD__);
        $formatData = json_decode($data, true);
        $url = $formatData['data']['url'];
        $client = new Client();
        $response = $client->get($url);
        $content = $response->getBody()->getContents();

        $connection->send($content);
    }

    public function onClose(TcpConnection $connection)
    {
//        var_dump(__METHOD__);
    }
}

配置文件

config/process.php

return [
    'async-task' => [
        'handler' => \process\AsyncTask::class,
        'listen' => 'text://0.0.0.0:8889',
        'count' => 20,
        'reusePort' => true,
    ],
];

启动服务

启动服务 php start.php start -d
查看状态: php start.php status

访问 http://127.0.0.1:8787 再查看状态

日志文件 runtime/logs/webman-2022-02-26.log 输出内容如下：

[2022-02-26 19:18:20] default.INFO: result:sleep 1, id:1 [] []

问题

为什么所有的异步任务，都放到一个async-task进程里执行了啊，怎么能平均或随机分配到20个进程里
