Right in the beginning you said the load was *exactly* 1.00. Now, load is 
defined as 

"the _number_ of processes on average waiting for the cpu in the last 1, 5, 15 
minutes"

So it does not mean that the cpu is necessarily working hard (but usually 
does) if the load is high. Yours is _exactly_ 1.00 (very suspicious)

This is almost certainly one of two things:

1. A stupid kernel config that you should not have done :-)
2. Some app is blocking hard on IO

I guess #2 - something waits for IO, it is not available, so immediately goes 
back to sleep waiting for it's next time slice. This happens many times a 
second and averaged over a minute looks like the cpu is constantly busy. Thus, 
no real extra cpu load is happening, the machine does not appear at all 
sluggish and the only harm is that it is annoying as hell.
