us: Time spent running non-kernel code. (user time, including nice time)
sy: Time spent running kernel code. (system time)
id: Time spent idle. Prior to Linux 2.5.41, this includes IO-wait time.
wa: Time spent waiting for IO. Prior to Linux 2.5.41, shown as zero.
/proc/loadavg
The first three fields in this file are load average figures giving the number of
jobs in the run queue (state R) or waiting for disk I/O (state D) averaged over 1, 5,
and 15 minutes. They are the same as the load average numbers given by uptime(1) and
other programs. The fourth field consists of two numbers separated by a slash (/).
The first of these is the number of currently executing kernel scheduling entities
(processes, threads); this will be less than or equal to the number of CPUs. The
value after the slash is the number of kernel scheduling entities that currently
exist on the system. The fifth field is the PID of the process that was most
recently created on the system.

Что-то я почитал ман, и не понял значений некоторых параметров в Summary Areatop - 13:45:59 up 17 days, 21:04, 3 users, load average: 1.05, 1.10, 1.08
Tasks: 97 total, 4 running, 93 sleeping, 0 stopped, 0 zombie
Cpu(s): 5.3% us, 2.0% sy, 92.7% ni, 0.0% id, 0.0% wa, 0.0% hi, 0.0% si
что означают us sy ni итп ? и в каких единицах измеряется load averege ?
