Linux and being speedy
(lemmy.world)
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.

This is the right answer. To complement it, I’d just say I’ve read someone before say that at Microsoft there’s no incentive to squeeze performance, so why bother if it won’t help you get promoted or get a bonus? All these things add up over time to make Windows only care about it when there is actually a huge bottleneck.
It’s also worth noting (for non programmers out there) that speed has no correlation with the amount of code. Often it’s actually the opposite: things start simple and begin to grow in complexity and amount of code exactly to squeeze more optimizations for specific use-cases.
