Besides Ubuntu 11.10 "Oneiric Ocelot" continuing to regress when it comes to increased power usage (new data from last week, plus also see motherboards with broken ASPM on Linux from yesterday) for many different systems, another area where Ubuntu 11.10 has regressed is with its boot speed. A clean install of Ubuntu 11.10 is definitively slower than previous Ubuntu Linux releases. Here's another look at the Ubuntu Oneiric boot performance along with some other new metrics to share as the official Ubuntu 11.10 release approaches later in the week.
With the planned release of Ubuntu 11.10 on Thursday, plus the Linux 3.1 kernel release being imminent, there's a number of new and interesting benchmarks that will be on Phoronix in the coming days and weeks (plus the usual increase in articles for the post-Oktoberfest season). In this article is another look at the Ubuntu 11.10 boot performance along with power consumption and other areas of system performance from Oneiric.
Lots of hardware is being tried with the pending release of Ubuntu 11.10, with most being affected by increased power usage (or at the same levels of Ubuntu 11.04 where it was already an increase over Ubuntu 10.10). It also seems very difficult to find x86 laptop, desktop, or server hardware where the boot time has not regressed in Ubuntu 11.10 using the stock packages and settings.
Some of these tests are even re-benchmarking every Ubuntu release going back to Ubuntu 8.04 "Hardy Heron" LTS.
