I'd be interested to see a (simple) script or log file so I can follow your
steps.
I tried repeating the same measurements (read() an entire file, readahead() the
entire file) for a variety of other file systems: XFS, JFS, Reiserfs. In each
case, the time taken for the read loop to complete and the readahead() system
call to complete were similar (10 to 15 seconds for a 1GB file).
