Here's an early look at some Bootchart numbers for two systems running Ubuntu 12.10 development snapshots compared to earlier releases.
Last month I provided Bootchart results from Linux 3.0 to Linux 3.6
with each major kernel release being timed. In this article are clean installs of Ubuntu 12.10 and earlier releases while measuring the performance.
More results will come when Ubuntu 12.10 is officially released later in the month, so this is just a preview.
The first results were from the ALUSA Atom Desktop with an Intel Atom D525 CPU and a 500GB SATA HDD. Ubuntu 12.10 was tested and compared to Ubuntu 12.04.1 LTS and Ubuntu 10.10. Ubuntu 12.10 booted in 31.78 seconds while Ubuntu 12.04.1 LTS took 45.49 seconds to boot. Ubuntu 12.10 is clocking in at around 31.78 seconds, which is an improvement over the earlier release but still slower where the Atom desktopw as running two years back. The maximum disk throughput during the process went from 53MB/s to 38MB/s to 77MB/s.
The next system was an AMD FX-8150 Bulldozer desktop backed by an OCZ SSD. For the faster desktop system, Ubuntu 12.04.1 LTS booted in just 6.58 seconds with a maximum disk throughput of 250MB/s. For Ubuntu 12.10, the maximum disk throughput is close at 249MB/s, but the boot speed regressed to 9.92 seconds.
Stay tuned for more Ubuntu Linux testing on Phoronix. Until then you can also see If You're Lucky, Ubuntu 12.04 LTS Can Boot Faster
