Smarty模板效率的问题！
最近用Smarty模板，发现会常用到file_exists，这是不是会增加IO的负担，这是不是不可避免的？

------解决方案--------------------
不会有影响，服务器比你想象的要强健的多
由于他需要将你的模板文件翻译成 php 程序，使用的时候 include 进来
所以当然要检查文件是否存在了，不但这个，他还要检查你的模板文件是否被你改动了，如果改动了，他还要重新翻译成 php 程序
如果你启用了缓存，他也要检查缓存文件是否存在，是否太旧了。以此来九鼎是直接使用缓存文件，还是重新生成缓存文件
------解决方案--------------------
与网络相关的 IO，比如没有缓冲的 echo 等
