The top command displays the dynamic statistics of a running Linux system in real time. Now, if the load becomes greater than the number of cores installed, then the processes would start to queue up to use the CPU. In this scenario, even if one of the cores is running at 100% capacity, the CPU would only be loaded with one quarter of its potential load. However, this metric scales with the CPU cores: The more cores installed on the system, the more tasks it can handle in parallel.įor example, for a CPU with 4 cores, the accumulated load average will be 4, since each core can handle a load value of 1. For example, a CPU with a load average of 1 is running at full capacity, whereas a completely idle CPU has a load value of 0. High load averages indicate an overloaded CPU with too many processes. CPU load, on the other hand, is a measurement of how many processes are being executed or waiting to be executed by the CPU.Ĭommands like uptime or top provide the value of CPU load averages-i.e., the average number of threads actively using or requesting to use CPU over the last 1, 5, and 15-minute periods. CPU utilization is the percentage of work the CPU is handling to manage tasks.
