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.

Brand new anything will not show up with amazing performance, because the primary focus is correctness and features secondary.
Premature optimisation could kill a project's maintainability; wait a few years. Even then, despite Ken's optimism I'm not certain we'll see performance beating a good non-cow filesystem; XFS and EXT4 have been eeking out performance for many years.
Cow is an excuse for writing performance, though the read is awful too currently
A rather overly simplistic view of filesystem design.
More complex data structures are harder to optimise for pretty much all operations, but I'd suggest the overwhelmingly most important metric for performance is development time.
At the end of the day the performance of a performance oriented filesystem matters. Without performance, it's just complexity
