Bootchart is a clever little tool that runs in the background as Linux boots. It collects details of all processes started along with disk usage and CPU statistics, and saves them to a log file. But that's not all. It then runs a small Java application that turns the log file into a highly readable performance chart ...

Based on the results, you can then look at optimising the boot process.

Installation
Bootchart comes ready-packaged for most of the major distributions or you'll find it available for download here. (Ubuntu users simply need to type sudo apt-get install bootchart in a console window.)

After installation, reboot the system and check out the charts in the /var/log/bootchart folder. Each time you boot a new chart is created, tagged with the date and a separate boot number so you can follow the effectiveness of your optimisations.
