I decided to install Ubuntu Dapper Flight-2 on a spare computer I had available. There are not any obvious differences between Dapper and Breezy at this early stage but one thing which does stand out is the performance improvements. My test Dapper and stable Breezy computers are exactly the same specification and the boot times for Dapper are vastly improved, currently 37 seconds (average) faster from power on to GNOME desktop than with Breezy. The graphical boot menu when booting from the install CD in a nice touch, I look forward to seeing how Dapper improves over the coming months. But right now there isn’t anything especially new, different or unusual to test.
