LAIKANXIAFUZAIDEDINGYISHIZENYANGDE：
In UNIX computing, the system load is a measure of the amount of computational work that a computer system performs. The load average represents the average system load over a period of time. It conventionally appears in the form of three numbers which represent the system load during the last one-, five-, and fifteen-minute periods.(wikipedia)
