Frequently Asked Question
Should I compile my own kernel? When is it worth it?
For 99% of users the distribution kernel is the right choice: it's tested, it comes with security updates, and it's compiled with sane defaults for the kinds of hardware most people have. You almost never gain measurable performance from a custom build.
Rolling your own makes sense in a few cases: you need a feature or driver that
isn't in your distribution kernel (you're running newer hardware than the kernel
knows about); you're doing kernel development and need to test patches; you're
building an embedded image and want to strip every unused driver to shrink boot
time and footprint. The workflow is roughly: git clone the kernel, make defconfig, make menuconfig to choose options, make -j$(nproc), make modules_install install, and add a bootloader entry.
