The release of Ubuntu 10.04 LTS "Lucid Lynx" is quickly approaching next month and it will arrive with a whole set of new features and improvements including a faster boot process, a long-awaited new theme, the Nouveau driver to replace the crippled xf86-video-nv driver, the unveiling of the Ubuntu One Music Store, integration of Plymouth, Ubuntu ARM advancements, and many other advancements for this Linux distribution. While it may not be as exciting as looking at these new end-user features, in this article we are testing out the available kernels for Ubuntu 10.04. Besides the standard Linux 2.6.32 kernel used in the Lucid release, there is also a specialized server kernel as well as a new -preempt kernel is now available. We are looking at how these different kernels perform and how they compare to the mainline Linux kernels with the 2.6.32, 2.6.33, and 2.6.34-rc1 releases.
