Watch out⚠️:fibonacci_cached.cache_clear()的作用是清除缓存,否则它会使用前面fibonacci_cached(20)的缓存结果,从而影响性能比较。 现实世界中的一个实例 假设我们正在开发一个基于Python的数据仪表板,该仪表板有许多用户。该仪表板显示中国5个城市的天气数据,并允许用户筛选和汇总特定城市的温度数据。

python的os.walk和系统tree命令在遍历目录时除了加载目录树还会加载文件的stat信息,所以文件一多就会占用很多buffer/cache。 find在遍历其他目录时只加载目录树不加域stat信息,所以不明显占用buffer/cache;但在遍历/proc时也会加载stat信息,所以/proc文件一多也会导致buffer/cache上涨。其实只是简单根据文件名的find不加...
