what are units of load average?
- zer0t3ch 10y agoI can't think of a good way to put it without just giving examples, so here goes: 1.0 = 100% usage of a 1-core system 1.0 = 50% usage of a 2-core system 4.0 = 50% usage of an 8-core system 8.0 = 100% usage of an 8-core system And IIRC, load average is represented usually as 3 numbers, which are over the last 5, 10, and 15 minutes.

- LukeShu 10y agoThe load average is calculated by the kernel (processes that display it just regurgitate the first 3 columns from /proc/loadavg); and yes, it is 1, 5, and 15 minutes.
- arnarbi 10y agoIt's the number of processes either running or waiting in the queue for CPU time. This is averaged over 5, 10, and 15 minutes. Load of 0 means idle (nothing to run), load of 1 means e.g. one process running and nothing in the queue. https://en.wikipedia.org/wiki/Load_(computing) https://en.wikipedia.org/wiki/Load_(computing)
