[OpenIndiana-discuss] Problem with high cpu load (oi_151a)

[Steve Gonczi]

i86_mwait is the idle function the cpu is executing when it has 
nothing else to do. Basically it sleeps inside of that function. 

Lockstat based profiling just samples what is on cpu, so idle time 
shows up as some form of mwait, depending on how the bios 
is configured.

if you're answering my question: I'm not guessing that much: I looked 
at lockstat output, and right there at the top we see i86_mwait 
consuming 45%(!) .
