kernel optimized for core 2 and later processors Debian/Ubuntu
I found some kernel images optimized for core 2 and later processsors. There are also some interactivity related improvements in this image. I thought someone might find them useful. Comments/suggestions welcome :) http://code.google.com/p/linux-kernel-core2/ Regards.

Wow, nice, thanks for sharing that info :) I take a quick look, seems like that kernel is patched with Con Kolivas patchset too.. which is also nice IMHO...since -ck is known to be a desktop friendly by lowering latency and increasing interactivity. BTW, swappiness=0? that means, hardly swap out IIRC. It can be good but it can be bad too IMO... during tight memory situation, it will cause paging do a lot that neccessary. I think better to make it 10 or 20, so paging out could be started right after it hits certain threshold. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com

The ck improvements are not total. BFS is not included. For swappiness, the default debian kernel uses 0. So there were no changes there. I guess with current desktops, swapping only when memory is full is reasonable... it is one of those tunings which is up for debate... you can still change it through sysctl.

Oh I see... well, BFS is nice IMO... once I use it...but somehow (not what caused it) one of my CPU cores disappeared from kernel detection :D

OK, I don't know that...thanks for letting me know. Assuming we're now have 2GB as standar, swappiness=0 is pretty safe...

For sure... :) Thanks again for the comments -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
