We are offering an exclusive kernel compiled by us, featuring many optimizations that we believe to be beneficial to our fellow folders. The nucleus of the kernel is in the form of two DEBs for Debian/Ubuntu.We tested the installation of this kernel in Ubuntu 9.04 and Linux Mint 7, and while there is an error emitted during installation, everything nonetheless works well. It is for Intel Core 2 machines and higher.
However, before you start installing these packages, we must inform you that:
- You install these packages at your own risk; it could be that the kernel introduces problems to your system. Such are the problems of running experimental kernels
- By using this kernel, you are not protected against security vulnerabilities that will be corrected in later versions (we'll try to update the kernel with critical vulnerability fixes)
- The performance gain is not guaranteed
- The change of variables in the system will mean that your OS will become slightly less reactive and prioritise background processes.

If you have an AMD processor, it will be necessary to recompile your kernel yourself using this tutorial.

This kernel has some scaling problems on BigAdv WUs and more than 8 cores ... we'll try to build a new one using a different basis (2.6.31 for instance).

Thanks for that toTOW. I don't have a Debian system at the moment so wasn't able to extract that myself. Some of this I already do to my kernel compiles (I rarely run a distro provided kernel). I'll have to play with the kernel timing and enable NUMA.

No special patches ... just adjustments in configuration options.
Here is the "changelog" :
Here is the "changelog" :
- Optimized Subarchitecture : ScaleMP vSMP (Virtual machines optimizations)
- CPU architecture optimization : Core2 / Xeon (instead of standard x86_64)
- NUMA Enabled (Memory optimization)
- Kernel timing set to 100hz (with 100Hz, kernel swaps processes every 10 ms (1/100). Default value is 1000Hz, every milliseconds. It reduces process swapping between cores, but might turn the system sluggish for everyday use, and using the computer might slow FAH down more than usual)
- CPUfreq forced to Performance mode (which implies Turbo Mode always on on i7 CPUs and helps to keep CPU at full speed under reduced loads, ie A1 core)

Good stuff guys, I will have to try this out. Did you apply patches to the kernel source or is it just variable changes?
