Mike Galbraith's Linux kernel patch that does wonders...

Last week I came across a blog post "The Linux desktop may soon be a lot faster" by Steven J. Vaughan-Nichols. It's about the patch done by Linux kernel developer Mike Galbraith who adds a mere 233 lines of code to the kernel's scheduler that cuts desktop latency down by a factor of ten. Even Linus Torvalds himself praised the performance boost he gets from the patch.

Two days later, another post appear on Google News. Alternative To The "200 Lines Kernel Patch That Does Wonders" Which You Can Use Right Away by Andrew. Lennart Poettering, a RedHat developer replied to Linus Torvalds on a maling list with an alternative to this patch that does the same thing yet all you have to do is run 2 commands and paste 4 lines in your ~/.bashrc file.

Everybody seems excited with the improvement. As for the champ at the bit, they've started implement the workaround and I believe some even recompile the kernel with the patch. Wow!!!
