This used to be the norm, not a weird thing that noone has thought of before. If you do this your kernel will be a lot smaller, boot faster, and be a bit more secure. Once you’re booted it won’t make any meaningful speed difference though.
It makes a HUGE difference in compile time. Which only matters if you’re building your own kernel anyway. It’s a solution for its own problem.
I think it’s a good learning experience though. There is genuinely a lot of stuff in there that you can easily, safely remove, and reading up on all the less obvious flags is fun.
I have doubts you would see any performance increases, and if you change your hardware you’ll be in for a tough time but it would be a fun learning experience!
Thats a question I have. I have two laptops, a shitty amd ryzen thinkpad t495 and a fancy soon-to-be-corebooted Clevo NV41MZ with i7-11** cpu. Pretty crazy performance difference although the chassis and keyboard suck. But if I get the keyboard I want to simply swap drives, as there is nothing fancy, this should just work right?
Swapping CPU manufacturers entirely? I’d just start my kernel config fresh. Pull up the old one next to a new (default ) one and go down line by line. Odds are there are at most a few flags that would need to be changed, but it’s a good chance to reevaluate your previous decisions too.
Can’t you compile your own kernel with exactly the things you want? Would be a fun project to do
True. Funny idea I should totally do this. This is how you learn Linux. Like a kernel for exactly your hardware specs!

Yep. When you have an 800mb HD and 16mb of EDO RAM, you only load what you need. The boot speed was unreal at the time compared to windows.

Um… I’m going to choose to phone a friend on this one…
Oh, …I have no friends who would know.
My instinct is you’re going to need to journalctl -b and see what modprobe and udev are up to.

I havent made any specific kernel changes, its just standard Fedora :D
