The ~200 Line Linux Kernel Patch That Does Wonders

Should also work for Ubuntu.

Hang on. So no performance boost for most of us?

No performance boost, just less performance decrease when your computer can't handle multitasking anymore. In other words; postponing the need to buy a new computer by a year or two.

Impressive shit

Why on earth was the test done with -j64... Use the amount of cores in the system. The test doesn't make sense otherwise. No one compiles kernels with -j64. Everyone uses the amount of cores plus something. Never 64.

I'm taking a wild guess here, but demanding more percentage of the time slicing cake? In other words making so many threads that it practically recieves 90% CPU time?

It was to simulate heavy load.

-j64 is not heavy load. It's ridiculous load that no scheduler patch should even try to address. Heavy load is something like -j18 on a 6-core machine, and -j6 on a dual-core. -j64 is useless. This is load that your desktop PC will never, ever reach. Not in a billion years.

Will it work with BFS, or do I need to switch to CFS?

Its only for CFS.

But I found that BFS =/= CFS + proc groups patch

BFS > CFS basic.

What kernel to I apply this patch against? It Failed against 2.6.37-rc2.

A quick test here shows improvement. I ran a kernel compile with j64 and the video playback is less stuttery. I just hope that people don't watch the video and get the impression that this is some magical pixie dust that will make their computers perform like the high end system that is used in the video.

Screw that. I don't wanna read half a book to do this.

Found exactly what I was looking for:

In Ubuntu even recompiling the kernel should be quick and easy!

So, vanilla + this patch performs better or worse than -ck patchset?
