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.

Gentoo's benefits come from having software specifically compiled for your specific CPU, which can take advantage of its quirks. Technically that's achievable with other distros as well; it's just a lot more work when it isn't built into your package manager. You can also eke out additional performance by building a custom kernel and removing various features that are meant to protect against bugs or security concerns, and while Gentoo doesn't push custom kernels as hard as it did twenty years ago, the capability is still readily accessible.
So: Gentoo makes it easier to access methods than can in theory be used to speed up any distro. The gains are either quite modest (for custom compilation) or not necessarily that good a tradeoff (disabling Spectre mitigations and other protections in the kernel). 🤷
