This command changes the length of time for which data is used to compute load statistics. The value is given in seconds, and must be a multiple of 30. The allowable range for interval is from 30 to 600 seconds. The smaller the value of the load interval is, the more accurate is the instantaneous rate given by load statistics. Smaller values may affect system performance.
