LTO Support Coming To Linux 3.15, Making For A Faster Kernel

How much faster? Like 1 to 3%? Or more serious improvements that can actually be noticed by the user.

Disregarding the average user, even a 1-3% increase in performance can spell wonders for places like super-computing and Android Phones. I bet it's more than that too, like sireangelus said: 600-800 is a 33% improvement, and it's an ~20% increase across the board.

if you go and disable useless thing and/or debug things from the kernel and compile your own ,i saw unigine valley go from 600 point to 800 points, by just optimizing the kernel .config . i would very much like to see a phoronix test about this, i used the pts to make a few standard vs custom kernel speed and i consistently saw a 20% speed improvement across the board.

...it was found the resulting Linux kernel image was faster in various benchmarks.

Phoronix: LTO Support Coming To Linux 3.15, Making For A Faster Kernel

As a potentially significant performance win for the Linux kernel, when compiling the Linux kernel support for link-time optimizations (LTO) are now supported...
