The ~200 Line Linux Kernel Patch That Does Wonders
Phoronix: The ~200 Line Linux Kernel Patch That Does Wonders
In recent weeks and months there has been quite a bit of work towards improving the responsiveness of the Linux desktop with some very significant milestones building up recently and new patches continuing to come. This work is greatly improving the experience of the Linux desktop when the computer is withstanding a great deal of CPU load and memory strain. Fortunately, the exciting improvements are far from over. There is a new patch that has not yet been merged but has undergone a few revisions over the past several weeks and it is quite small -- just over 200 lines of code -- but it does wonders for the Linux desktop.
Will this increase performance on my old AMD Athlon XP machine, or does it only really help those with multicore cpu's?
So now it will actually be practiical to multitask in linux?
It doesn't seem like this would make much difference to general users who aren't running big jobs in another tty though, it's a pretty specific use case. Most of the big jobs I run are on another machine through SSH. Still pretty awesome though.
Hang on. So no performance boost for most of us?

I take you're implying Windows? I hope not. Let me just go ahead and say that Linux has always been better at multitasking than Windows. Regressions in Linux are in their own league.

Besides, this is NOT about multitasking, it's about responsiveness. An entirely different thing
