Linux Load Average Deep Dive
Do you really understand load average?

Every time we find that system is slow, the first thing we usually do is to run the top
or uptime
command to understand the load of the system, for example:
$ uptime
02:34:03 up 2 days, 20:14, 1 user, load average: 0.63, 0.83, 0.88
But what I want to ask is, do you really know what each column of output here means?
