Why does starting xfs do a find ? Me thinks we can save a few cycels there.

What happens to overall boot time if rhgb and dhclient is disabled, with and without readahead?
I already posted some results with different rhgb/readahead combinations. Before I try all other options, I'd much rather complete the work, put it online and let people try it out. Some of the issues seen in these charts (e.g. 'modprobe floppy') are specific to my laptop.
Also interesting would be a graph of a minimal boot â disable all nonessential services; portmap, rpc, gpm, cups, etc. â into text console. It'd reduce the ânoiseâ in the graph and might reveal something interesting about the remaining processes.
Ha, no horizontal bar for this one: http://www.klika.si/ziga/bootchart/bootchart-minimal.png
That's with runlevel 3 and only the following services: xfs, iptables, messagebus, irqbalance, syslog, haldaemon, crond, atd, anacron, cpuspeed, xinetd.
Exit criteria are mingetty running and system idle.
Oh, BTW, what is that apparent zombie of S04readahead_early? Just a timing issue with the sampling?
If you take a look at the log file that produced the image (http://www.klika.si/ziga/bootchart/bootop.log.rhgbfix.gz):
