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,
