一直不太理解为什么用了smarty还要用memcache~~~~
都说smarty + memcache配合用是很好的优化组合，但我不明白为什么用了smarty还要用memcache~
因为smarty不是有页面缓存吗，比如现在有个页面A，我规定它缓存的时间是10分钟，那它只要每十分钟逻辑运算一次就可以了。还要memcache有什么用呢？
能给我举个小例子说明smarty和memcache在什么情况下配合使用吗？
谢谢各位！
------解决方案--------------------
存的地方不一样，memcache是存到内存中的，smarty是存到硬盘上的，读数据肯定是从内存中读取快，你看哈这2个的原理吧
------解决方案--------------------
既然smarty可以cache了。为什么还要用 memcache ？
------解决方案--------------------
这个道理很简单：由于运行机制和适用范围的不同，smarty 只被少数初级php程序员使用；而 memcache 被广泛的采纳，并由此衍生出基于内存的数据库系统
------解决方案--------------------
一个是针对数据，一个针对的被访问的页面，例如最长用的方式将查询出来的条数据存入memcache，而有些页面实时刷新要求不高的那么就smarty的缓存了，作用的范围不同，就像你吃了胡萝卜还要吃西瓜差不多，吃胡萝卜是增加维生素C，吃西瓜是增加维生素D，这个如果还迷糊，你可以先不必纠结，等以后慢慢就知道了
------解决方案--------------------
两个不同的东西...像kyzy说的。虽然都说是为缓存服务，但是缓存的具体对象和实现方法不太一样。虽然经过各种SM后也能够彼此通融些，但是就有点脱裤子了。
简单说smarty缓存最终的结果.memcache缓存中间的部分.当然这样说也比较笼统，但多少你能知道他们不是为了解决相同问题的交集。
------解决方案--------------------
smarty 的 cache 是基于文件的，可称为 filecache
访问文件肯定要比访问内存要慢
所以才有 smarty + memcache 一说
也就是说可以修改 smarty 将 cache 放到 memcache 中去
至于用什么，怎么用，那都是方案问题。与实现技术无关

After joining the company, I understood what Cache is
Jul 31, 2023 pm 04:03 PM
The thing is actually like this. At that time, my leader gave me a perf hardware performance monitoring task. During the process of using perf, I entered the command perf list and I saw the following information: My task is to enable these cache events to be counted normally. But the point is, I have no idea what these misses and loads mean.

The details are as follows: 1. Let’s talk about what is hard-coded cache? Before learning SpringCache, I often used caching in a hard-coded way. Let's take a practical example. In order to improve the query efficiency of user information, we use caching for user information. The sample code is as follows: @AutowireprivateUserMapperuserMapper; @AutowireprivateRedisCacheredisCache;//Query users publicUsergetUserById(LonguserId){//Define cache keyStringcacheKey= "userId_
