My stepbrother has been complaining that his computer is slower than normal. He wasn't dangerously low on disk space, and he has plenty of ram for the things he does. So I opened the terminal and ran "top". At the bottom, under kernel_tas, there was another thing running called "idle_threa". It said it was using 88% of the cpu, and it had a PID of 0. I was wonder if this is normal (it's not on my computer) and how to fix it if it's not.
Thanks.

"idle_thread" is just idle. It represents how much CPU you're not using. I don't think it's the source of the problem

Okay, thanks. Any idea what it could be then?

Not without seeing more details.

How much RAM does he have, how much hard drive space is available, what type of computer is it. processor speed, etc...
