Right. Did you see if readahead helped?

I suspect the makemode of startpar might work better. It is not
enabled yet. I have to spend some time to test it, as it require a
rewrite if init.d/rc. It checks the system load and will start things
based on the declared dependencies, not the sequence number. This is
how insserv and startpar is used by the authors, so I suspect it is
the optimal way to do it. :)
I am still curious on your boot sequence, though.
Happy hacking,
