"At the top of the feature list for this new distro is
something that all users will notice, namely faster boot times --
specifically a claim for a 20 second startup. Faster startup is a
key goal for Linux distros this release season, Ubuntu Jaunty which
should be out at the end of April, also features a faster startup.
"Fedora is also aiming to have the new ext4 Linux filesystem as
the default for new Fedora 11 installations, which will not only
aid boot times but performance of the distro overall."
