Interesting distro to try, or to try again

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 is a distro that you compile all the packages ( atleast used to be that ) where you compile packages with flags that optimize those for your exact cpu.
Also allows you to strip out features from packages while compiling like X11/wayland uf you don't use either.
This can help a lot in general performance of your system.
You can use binary packages for x86_64-v3 and it will already use a lot more modern CPU instructions, and it will still compile single packages from source if you change the USE flags to something the binhost doesn't have.
It certainly doesn't "defeat the whole purpose of using Gentoo".
I used to strip out more than half the features those packages provided that I didn't need, so it does for my usecases.
What percentage of packages?
100%, I use to do global use flags at '-*' and then set minimal amount of flags till I get something working.
Spent a whole day doing that.
And how much time did you save from the performance gains?
Wouldn't know, because at the time I was by my pc maybe 30 mins a day because of my job, so I just let my system compile in my 13 hours work time so just never tested that stuff out.
I do know that it felt snappy always.
“100%” which would include those that either don’t have any use flags or all of them disabled by default/masked where -* wouldn’t do anything. pkgconf for example. Uh huh, yeah right.
