In December we wrote that Ubuntu 10.04 already shortened the boot time, which has been a great focus amongst Canonical and Ubuntu developers as they strive for a ten second boot. A lot has changed since that article was published last year, including the introduction of Plymouth and many kernel mode-setting improvements along with the introduction of Nouveau for NVIDIA KMS support. We've ran a new boot performance comparison on two laptops and a netbook as we see how the boot times are looking with Ubuntu 10.04 LTS when compared to Ubuntu 9.10. We have also looked at how the power consumption has changed in the Lucid Lynx for these mobile devices.
