> ... Quite a bit of Haiku's boot time can be attributed to
driver/hardware recognition and initialization. The USB stuff alone takes
several seconds on my machine. ...[[BR]]
Is there are any profiling software for Haiku? How about adding time
information to syslog?[[BR]]
> Anyway, I guess the main points for boot time optimization are (1) more
intelligent I/O (e.g. precaching) and (2) choosing drivers for hardware
more directly (e.g. by PCI device ID) instead of trying all of them.
Furthermore it would be great, if it was possible to recognize earlier
whether the boot volume requires USB and postpone USB initialization if
not.[[BR]]
There is one more way for boot time optimization: http://dev.haiku-
