Here's the third line of top on my system:

Cpu(s): 1.3% us, 0.3% sy, 0.0% ni, 98.3% id, 0.0% wa, 0.0% hi, 0.0% si

I can work out us, sy, ni and id (user, system, nice, idle), but what are
wa, hi and si?
The answer does not seem to be in man top.
SuSE 9.2, "entirely new and enhanced" top.

They're time-scaled values from the first line of /proc/stat, defined in
linux-2.6/fs/proc/proc_misc.c:show_stat():

seq_printf(p, "cpu %llu %llu %llu %llu %llu %llu %llu\n",
(unsigned long long)jiffies_64_to_clock_t(user),
(unsigned long long)jiffies_64_to_clock_t(nice),
(unsigned long long)jiffies_64_to_clock_t(system),
(unsigned long long)jiffies_64_to_clock_t(idle),
(unsigned long long)jiffies_64_to_clock_t(iowait),
(unsigned long long)jiffies_64_to_clock_t(irq),
(unsigned long long)jiffies_64_to_clock_t(softirq));

I doubt you'd see the last three figures nonzero except in really
unusual high-load situations, myself.

Very nifty cool program it is, although the manpage is winceworthy.

Try, e.g., this .toprc: (hit `A' and then `_')

RCfile for "top with windows" # shameless braggin'
Id:a, Mode_altscr=0, Mode_irixps=1, Delay_time=3.000, Curwin=0
cpu fieldscur=AEHIOQPTWKNMXbcdfgjlrsuvyz
winflags=64944, sortindx=10, maxtasks=0
summclr=3, msgsclr=2, headclr=1, taskclr=2
tme fieldscur=ABCefGjlrstuvyzMKNHIWopQDX
winflags=64824, sortindx=12, maxtasks=0
summclr=3, msgsclr=2, headclr=1, taskclr=2
mem fieldscur=ANOPQRSTUVXbcdefgjlmyzWHIK
winflags=64824, sortindx=13, maxtasks=0
summclr=3, msgsclr=2, headclr=1, taskclr=2
