You might be able to speed up the read by playing with the vfs.read_max

Wow! That makes a huge difference, thanks. Should this not be in 'man tuning' ?
AFAIK vfs.read_max will only influence sequential reading - it's the
readahead size. Also, it's still unexplained how increasing it yields
performance better than that of 'dd' on a raw device.
