laravel pusher运行非常慢

Question

我遵循了本教程： 使用LARAVEL构建聊天应用程序

但是当我在php Controller中跟踪持续时间时， broadcast()和event()函数的作用非常缓慢，为2〜8秒。 顺便说一下，没有错误消息启动。

我想这不是正常情况，websocket是否应该实时工作？ 甚至我将DEBUG更改为true或false都没有改变。

我不知道laravel + pusher应该有多快。 他们只是被称为“实时”，难道它们不应该以0.0秒左右的速度运行吗？

有人可以提供建议吗？

**我只是再次测试。 广播时间约为0.8秒，从客户端发送POST到客户端的Listener处理的广播的整个持续时间约为1秒。 抱歉，我无法重现昨天发生的性能下降。 对于Pusher，这种性能正常吗？ 谢谢！！

Answer 1

我发现queue.php的default queue.php指向sync ，这仅适用于开发人员。 将default更改为用于生产的database ，函数broadcast()更改为约0.01秒。
