Tweaking the kernel
Tweaking the kernel
Does anyone here modify their kernels for better performance? I read somewhere today that it can be done. Something like removing unnecessary drivers.

Re: Tweaking the kernel
A driver won't be loaded if the hardware is not detected, so.... You can speed up compilation and make the kernel package smaller by pruning unused drivers, but that's about it on that front.
You could get into tweaking schedulers and latency like the Liquorix kernel, though.

Re: Tweaking the kernel
Many years ago tweaking a kernel could produce noticeable results. That was back when a "blazing fast" CPU was a 486.* Those days are gone. On modern machines you can tweak to your heart's content but to see the results you need before and after bench tests.

There's very little that Liquorix hasn't done to try to optimize performance for desktop (as opposed to server) use.
That said, I echo the general sentiment that hardware is "the" driving force in kernel performance, and has been for at least 10 years.
I've not done any defensible research on the question, but my educated speculation is that Liquorix's "performance boost" is largely perceptual; that is to say, it appears faster, subjectively speaking, but in reality, the total time that a given takes to execute is still roughly the same, start-to-finish.
But again, that's just speculation. (And just to be clear, apparent speed-up is not a bad thing.)
