I came across the cool bootchart program today. This creates an extremely nice Gannt-chart-like graph of the processes running during bootup, CPU and disk utilisation and so on. So I set it up on my machine, to see how my parallel patch for file-rc fared.

Here's the chart. It looks like my parallel file-rc is doing quite well, with 21s bootup times and excellent CPU and disk utilisation in the main startup period. I should probably ditch ntpdate or background it, and look into why hwclock is so slow - without these 15s or better is easily within reach. Nor is my machine that lightly loaded, with squid, cups and apache in the startup list.
