From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Seems like a measurable improvement although not dramatic in most benchmarks.
I think we may be looking at these wrong. Yes there's a visible throughput/latency improvement here but what about other factors? Power savings? Cache efficiency? CPU cycles saved for other co-running processes?
These are going to be pretty hard to measure without an x86_64 simulator. So I don't fault them for not including such benches. But there might be more to the story here.
