There's a 20 MB load of files in your readahead list and they are being
read for 15 seconds. I guess a 26.60 MB/sec 'hdparm -t' suggests room
for improvement? Note that this is on a 4200 RPM drive.
hmm yeah there ought to be room; I'll need to think about how to use that
though.
One question: was the drive (light) mostly quiet when readahead was finished ?
