"Bootchart is a handy utility which allows you to audit
the boot sequence of your computer. It generates an attactive chart
of the processes that are run at bootup, how long they take to
initiate, and what resources they use. Armed with this information,
you can identify the processes which take a significant amount of
time to load, and then decide whether they can be removed.
"Bootchart is not installed by default in Ubuntu, but this is
easily rectified by installing it in the usual way with the
Synaptic Package Manager.
"The auditing is performed early in your boot sequence, and
records system statistics as your computer boots.
"When the boot loader starts, select the relevant kernel you are
booting, press 'e' to edit the commands,and add the following to
the kernel line: init=/sbin/bootchartd
"After booting, the software will have created a .png graphic
chart in /var/log/bootchart/"
