process.memoryUsage.rss()

• 返回：<integer>

  ¥Returns: <integer>

process.memoryUsage.rss() 方法返回以字节为单位表示驻留集大小的整数 (RSS)。

¥The process.memoryUsage.rss() method returns an integer representing the Resident Set Size (RSS) in bytes.

驻留集大小是进程在主内存设备（即总分配内存的子集）中占用的空间量，包括所有 C++ 和 JavaScript 对象和代码。

¥The Resident Set Size, is the amount of space occupied in the main memory device (that is a subset of the total allocated memory) for the process, including all C++ and JavaScript objects and code.

这与 process.memoryUsage() 提供的 rss 属性值相同，但 process.memoryUsage.rss() 更快。

¥This is the same value as the rss property provided by process.memoryUsage() but process.memoryUsage.rss() is faster.
