Ubuntu 9.10 boot optimizations: 5 second startup with an SSD
I installed Ubuntu 9.10 alpha 6 on a Dell Inspiron 1420n, the Ubuntu laptop that I reviewed in 2007. I conducted extensive startup performance testing and used the bootchart utility to measure the results. My average boot time was 22 seconds, with Xorg starting roughly 13 seconds into the boot process.
Users with solid state drives will see a far more dramatic improvement in boot performance. Canonical external developer relations coordinator Jorge Castro (a former Ars Linux contributor) supplied us with a boot chart from his computer, which has an SSD and boots Karmic alpha 6 in only five seconds. If you examine his chart, you will see that Xorg comes up in only two seconds.
