How long does it take to compile Linux kernel?

The Linux kernel takes around 5 minutes (without modules) to build on an Intel Core i5 Jasper Lake mini PC with 16 GB RAM and a fast SSD based on our recent review of Beelink GTi 11 mini PC. Kernel developers may have to build for different targets and configurations, plus all modules so the build times may add up.

Why does Debian use old kernel?

It’s because the distribution maintains the kernel by backporting all the important fixes to its kernel. In other words, your Linux distribution makes sure that your Linux kernel is patched well and has all the bug fixes and important new features backported to it.
