这使用workerman的gateway框架的时候遇到的疑问

   //redis的初始化

   }
}

RedisDB.php

<?php
namespace Server\Library ;
class RedisDB
{
    static $_instance; //存储对象
    public $handler;
    private $config = null ;
    public function __construct($redisConfig , $dbindex = 0){
        if (!extension_loaded('redis')) {
            throw new Exception("REDIS NOT  SUPPORT", 1);
        }
        $this->handler = new \Redis();
        //从配置读取
        $this->handler->pconnect($redisConfig['hostname'], $redisConfig['port']);
        $this->handler->auth($redisConfig['auth']);
    }

    public static function getInstance($redisConfig , $index = 0)
    {
        if (!isset(self::$_instance[$index]) or FALSE == (self::$_instance[$index] instanceof self)) {
            self::$_instance[$index] = new self($redisConfig , $index);
        }
        return self::$_instance[$index];
    }  
}

start_businessworker.php
我开启了

$worker->count = 8;

疑问：

这初始化redis的连接的时候，我发现会new redis连接8次

id=1017 addr=192.168.2.188:56012 fd=9 name= age=659 idle=659 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=0 obl=0 oll=0 omem=0 events=r cmd=auth

但是我上面 初始化连接之后只是赋给一个类的静态变量。这样的话 那岂不是只有1个连接？？？？
难道根据worker的id进行吗？
请指教

上面我redis连接使用了单例的模式！！！！
