https://bugzilla.kernel.org/show_bug.cgi?id=54271 --- Comment #3 from Michael Kerrisk <mtk.manpages@xxxxxxxxx> 2013-02-25 20:55:17 --- So, I'm no expert here, but on my system (ext4), reading a 1 GB file (with large userspace buffers) takes about 12 seconds. Doing a readahead() of a 1GB file also takes about 12 seconds. If I'm understanding what you are saying correctly, the readahead() should return much faster than the file-read case.
