I'd like to find out what takes the most time in my boot process from GRUB to the Ubuntu login screen. How can I profile my boot process to find out what's taking so long?

My EC2 (Ubuntu 12.04 server) took about 1 min to boot (defined as the time between power-on and all the daemon processes are started). I need to cut down the time to boot. My guess is that the total time depends on kernel boot time and the time to start all the daemons.
Kernel doesn't seem to take much time (the following is from my kern.log) and it showed it didn't take about 14sec.
