Time was until gnome applet showed up, so on my system readahead did not improve boot speed at all.

Note that there is a bug that prevents readahead-collector from starting if you have selinux disabled, since the /.autorelabel file is still hanging around during reboots, I had to remove this file for collector to work.

1) The rhgb removal is a big step forwards, rhgb slows down things a lot.
2) One major thing to look at I think is the initrd and udev, these take really a lot of time 3) Get rid of that sysinit stuff and start using upstart jobs, I still have not seen any progress on this.

Can you provide a bootchart for your system?
Best would be 2, one with and one without readahead
