[opensuse] Custom kernel for performance: does it makes sense?
Hi. If you build a custom kernel specifically for an atom based netbook, can you gain a "noticeable" improvement? It doesn't matter the kind of improvement gained: lower temperatures, better interactivity, lower memory usage, ... whatever. I used to build custom kernels long ago, but it was more for fun and to learn something. Now the kernel have a lot more options than those days but It doesn't seem to be more complicated. I know the hardware and I can uncheck most of the options, but I don't know if that would make any difference because most of them are build as modules. And to finish, do CFLAGS and gcc flags do something. I don't know why, but I think that I read long time ago some document in the kernel source saying it doesn't matter at all. I may have imaginated it, XD. Greetings. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Ok. Time saved, XD. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Building a custom kernel for performance is typically only necessary when dealing with ridiculously low resources. The other primary reason to compile a kernel is to include support for new or legacy hardware.

Or when a small improvement is important. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
