For each file in a given directory, the Master created a WorkUnit, providing it with location of the file it was to process.

对于指定目录下的每个文件，Master都创建一个WorkUnit，向它提供要处理的文件的位置。

youdao

From a performance perspective, we didn't want Terracotta to have to synchronize access to these WorkUnit attributes if the Master will never access them.

从性能角度来看，如果Master永不访问WorkUnit的属性，那么我们是不希望Terracotta对这些属性的访问进行同步的。

youdao

For in a more realistic and complex example, the WorkUnit may have many instance variables that are really only relevant when it is being run by the Worker.

举一个更为现实和复杂的例子，WorkUnit可能有很多实例变量，它们实际上只在由Worker运行的时候才是相关的。
