"Dave Jones currently lives in London, employed by SuSE
as a Linux kernel hacker. In the past six months since he graduated
from the University of Glamorgan he has gotten involved in an
impressive range of kernel related projects, including Powertweak,
x86info, OProfile and the Kernel Janitors Project. Additionally, he
maintains a -dj patch for the 2.5 development kernel, helping to
sync it with the stable 2.4 kernel as well as offering increased
...There's no quick and dirty "Make my system fast"
button. A misconception people have is that by loading up the GUI
and turning everything on or up to its maximum their system will be
faster, stronger, better..
The real answer would be to find out what the specific problem
you are experiencing is, and then hopefully, you'll find one of the
plugins provides the functionality to tune that feature. Use the IO
elevator plugin to test for disk I/O improvements for example. The
elevator plugin is a good example of why "everything on 12"
approach is a bad thing, as by increasing the size of the buffer to
be sorted may end up with a more linear path, the latency involved
during the sort may have killed any potential win. So some things
are a balancing act to be decided by the users preference.
Some other things are more obvious.. A badly programmed BIOS may
forget to enable performance related bits in CPU registers perhaps.
Or maybe PCI bridge registers. Sometimes (although become more rare
these days), BIOS writers play it safe, and leave features in their
"off" state if there's a known hardware compatability problem. Even
if the system doesn't contain that hardware. So some of the more
experiemental hardware based tweaks are of a "Trial and error"
approach, although Powertweak can give warnings if certain tweaks
shouldn't be applied on the current system, as it generally has a
better view of the hardware than what the BIOS has been programmed
to look at."
