But it doesn't seem to be working without a tty
I thought that might be a problem. Thanks for fixing it up.
iotop -b -o -n 5
Thanks. I think -n 1 is better; -n 5 is too much information.
But the 7 cpus look mostly idle.
I think it is almost certain that the underlying problem is disk I/O.
That's been clear to me for quite a while, since the top processes are
almost always in disk wait, as I said. What's not clear is how to
resolve it, given that updating hardware is a massive, expensive, and
unlikely-to-happen project.
