In this article, we are looking at Ubuntu's boot performance for the past five releases through the use of Bootchart for measuring its boot time, disk throughput, and the running processes.

Even with many new features and additions appearing in every new Ubuntu release, it's gratifying to see the boot time continuing to drop. While our Ubuntu 8.04 build was three seconds slower than Ubuntu 7.10, it was a development build and we would expect further optimizations to occur prior to the April release of Hardy Heron. With Ubuntu gearing up to increase their presence on mobile Linux devices, the boot time will become increasingly important so we would expect optimizations not only now but in the long-term as well.
