os.loadavg() 方法返回一个数组,包含 1、5 和 15 分钟平均负载。

平均负载是系统活动的测量,由操作系统计算得出,表达为一个分数。 一般来说,平均负载应该理想地比系统的逻辑 CPU 的数目要少。

平均负载是 UNIX 相关的概念,在 Windows 平台上没有对应的概念。 在 Windows 上,其返回值总是 [0, 0, 0]

The os.loadavg() method returns an array containing the 1, 5, and 15 minute load averages.

The load average is a measure of system activity, calculated by the operating system and expressed as a fractional number. As a rule of thumb, the load average should ideally be less than the number of logical CPUs in the system.

The load average is a Unix-specific concept with no real equivalent on Windows platforms. On Windows, the return value is always [0, 0, 0].
