It seems that I'm not at all diskbound. When I repeatedly dd a 10GB
from from the 16GB memory of one of my storage servers I consistently
max out at around 390MB/s with _zero_ disk io involved. I imagine I'm
doing something wrong in terms of juggling cache sizes, io threads,
readahead sizes etc that is causing this? Or is there some other OS
interaction interfering?
