"We have boot-time benchmarks of the latest Ubuntu 9.04
work along with Linux desktop benchmarks comparing it to its
predecessor, Ubuntu 8.10...
"Is Ubuntu 9.04 booting faster than its predecessor? With the
Intel Atom netbook at least, it is a resounding yes! It took 29
seconds to boot Ubuntu 8.10 but only 21 seconds for Ubuntu 9.04
Alpha 4. Bootchart measured these results, all settings were left
at their defaults, and in each case we did a clean installation of
Ubuntu occupying the entire solid-state drive. Had we switched to
using the EXT4 file-system the Ubuntu 9.04 performance may have
been even better. Below are the Bootchart graphs for Ubuntu 8.10
and 9.04, respectively."
