Just interested what’s done during my system start-up, I benchmarked it with bootchart. Here is my result for an encrypted Ubuntu 8.04 amd64 start-up. My hardware/software statistics (for you to compare):

  • CPU: Intel T7600
  • Memory: 2GB DDR2
  • Init: upstart-0.3.9-2
  • Kernel: 2.6.24-19

Remark: You have to subtract 2 seconds from the start-up which I needed to type in the password for the encrypted partition, so the start-up time results in 41 seconds. Through tests I found out, that the first passage where CPU+disk sleep simultaneously is the time where you type your password, the second one is always 5 seconds long and not giving any sense to me at the moment.
