I am using a machine that has using

cat /proc/cpuinfo | grep processor | wc -l

returning 8

I am trying to load the server using a load generator that I wrote, and capture the behaviour of TOP command for idle (as the software that is tested on server runs on ROOT). Doing the load as an increasing step function, I capture the idle state every second, and see the result. Strange thing is that when I increase the load every 1 minute, the idle state is infact increasing (??). This honestly does not make sense .. I thought with more load, the idle state will decrease, and the cpu usage will increase. Is there any reasonable explanation for this behaviour, maybe for the server utilization itself?

Thanks for any feedback

-- ok, no idea for the down vote. but I try to find this behaviour a lot, can not find any reasonable things to explain this ..
