下面thinkphp框架教程栏目将给大家介绍关于TP执行方法要引入这么多个文件对性能的影响，希望对需要的朋友有所帮助！
具体问题：
thinkphp为啥执行一个方法要引入这么多个文件，对性能有何影响？
如题，在thinkphp中某方法只输出一个echo 1, 发现要引入的文件很多，这对服务造成什么影响。
遇到并发大时候该如何优化？

}网友回答：
使用框架本来就是牺牲些性能获取开发效率的。TP框架内部耦合度很高，因此性能比起其他框架还好呢。
看上面加载的文件，你应该使用的是TP5，TP5中使用到的是懒性加载，这种方式只在需要的时候才加载相关的类文件，相比于3.x性能上提升了不少。
另外一种就是缓存。TP3.X能够将所有的要包含的文件打包成一个文件，这样就避免了多次加载。不过在TP5是模板才有缓存。
高并发下，可以使用APC，提高硬件，使用nginx之类。
以上是探讨关于TP执行一个方法对性能的影响的详细内容。更多信息请关注PHP中文网其他相关文章！
