I've run this test again.

What happens is when I unpause I get a quick stream of errors and then 
the problem goes away. So by using a 10s pause at least I can watch tv 
at the moment without it getting on my wick.

On the backend I am getting very low IO wait according to top - between 
1-2% on just one of the 2 cores.

On the frontend I am getting huge IO wait, about 30% across 2 of the 4 
cores.
