Ubuntu 11.04 "Natty Narwhal" is set to be released on Thursday
and while there are a number of new features to talk about in this
latest release, the Phoronix Test Suite software has been busy analyzing
the performance of this latest release. There is open-source graphics
driver improvements leading to some performance improvements (such as
Radeon KMS page-flipping), the famous ~200 line Linux kernel patch to
improve responsiveness, and various other enhancements that catch our
fancy in Ubuntu 11.04. However, one area where there is a frightening
regression in Ubuntu 11.04 is with its power consumption. For mobile
devices in many workloads, Ubuntu 11.04 is consuming noticeably more
power than in any of the past Ubuntu Linux releases. Sadly, no one seems
to have noticed in time since continuous integration testing on Linux
seems to happen so haphazardly right now.
