I am trying to optimise the boot-up time of linux on an embedded device (not PC)

Currently to profile the boot-up sequence,
I have enabled the timing info on printk logs.

Is this the most optimum way?
If not, how do i profile the boot-up sequence (with timing) with minimum overhead?

PS:
I have a terminal (of the device) over a serial-connection &
I use TeraTerm over windows-XP to access it.
