How load average is calculated?
Systems calculate the load average as the exponentially damped/weighted moving average of the load number. The three values of load average refer to the past one, five, and fifteen minutes of system operation. Mathematically speaking, all three values always average all the system load since the system started up.
How much load average is too much?
The “Need to Look into it” Rule of Thumb: 0.70 If your load average is staying above > 0.70, it’s time to investigate before things get worse. The “Fix this now” Rule of Thumb: 1.00. If your load average stays above 1.00, find the problem and fix it now.
What is the load average for the last 5 minutes?
So the number shown above means: load average over the last 1 minute is 3.84. load average over the last 5 minute is 3.72. load average over the last 15 minute is 2.41.
What does a 0.5 load average mean?
Applying that to the load average output (0.5, 1.5, 3.0) that we got above: 0.5 means the minimum waiting time at the counter. Between 0.00 and 1.0, there is no need to worry. Your servers are safe! 1.5 means the queue is filling up. If the average gets any higher, things are going to start slowing down.
What’s the difference between system load and load average in Linux?
System load/CPU Load – is a measurement of CPU over or under-utilization in a Linux system; the number of processes which are being executed by the CPU or in waiting state. Load average – is the average system load calculated over a given period of time of 1, 5 and 15 minutes. In Linux, the load-average is technically believed to be

What should the load average be on a server?
A load average of 6.03 would indicate a system with a single CPU was massively overloaded, but it would be fine on a computer with 8 CPUs. The load average is especially useful on servers and embedded systems.
