php – Laravel REST API和高CPU负载

我注意到,CPU总共进行了1700次请求,一次只有2次,提高到70-90％.

我是一个完整的php和laravel初学者,我已经使API跟随this tutorial,也许我可能在做错了,或者只是一个概念缺乏最佳化的证明.我如何改进这个代码？ (启动函数是getGames)
你认为所有问题的根源是Laravel还是应该获得相同的结果甚至改变框架/使用原始的PHP？

UPDATE1我还设置了一个文件Cache,但CPU负载仍然是?50％.

UPDATE2我将查询速率设置为每500ms两次,CPU负载降低到12％,所以我猜这个代码缺少队列处理或类似的东西.
