所以，task的第一次执行时间包含装载它使用的所有类的时间(如果这些类还没有装载的话)。

So, a task's first execution time includes the loading of all classes it USES (if they're not already loaded).

read _ file函数使用stat函数调用检查文件的修改时间，只有在上一次装载之后修改了文件的情况下，它才重新读取文件的内容。

The read_file function USES the stat function call to check the modification time of the file, only re-reading the contents of the file if it changed since the last time the file was loaded.

装载分为两部分的变量到高速缓冲将花费双倍的装入时间，因为不能一次装入。

Loading a variable that splits over two cache lines takes the double time of loading one that does not.
