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.

IMO there's no point in optimising without being able to measure the results.
A profiler should be able to tell you how much time is spent running the code you're attempting to optimise. It might turn out that the wine runtime code is not a significant factor in performance.
I bet Phoronix has benchmarks of this
i searched phoronix and found nothing, they did other programs whenever a new gcc version launched, they compiled a lot of benchmarks with different flags and measure compile time and program performance, some programs gained a noticeable with -O3 -march=native
