Linux Kernel Build Times Ready To Be Significantly Reduced With Latest Patches
A new series of patches aims to significantly reduce Linux kernel build times by addressing bottlenecks identified with AI assistance. The latest revision, posted by Arm engineer Lorenzo Stoakes, is targeted for inclusion in the upcoming Linux 7.4 release. Testing on various hardware platforms, including Apple Silicon and AMD processors, shows substantial improvements in compilation speed.
- ▪AI assistance helped identify major bottlenecks in the Linux kernel build code that the new patches address.
- ▪The third revision of the patch series consists of 20 patches posted by Lorenzo Stoakes for the Linux 7.4 cycle.
- ▪Tests on Apple M2 hardware showed a 55% speedup for incremental builds with Clang and a 74-76% speedup for no-op builds.
- ▪Similar performance gains were observed on AMD EPYC and Threadripper systems, confirming the broad applicability of the optimizations.

Linux Kernel Build Times Ready To Be Significantly Reduced With Latest Patches Written by Michael Larabel in Linux Kernel on 18 September 2026 at 06:26 AM EDT. Add A Comment The past few weeks we have eagerly been following a Linux kernel patch series after AI found some major bottlenecks in the Linux kernel build code. With AI helping to address these bottlenecks, Linux kernel build times are substantially reduced. These optimizations might be ready in time for Linux 7.4 for reducing incremental kernel build times as much as around 70%. This week the latest iteration of these patches were posted by Arm engineer Lorenzo Stoakes. The third revision is a set of 20 patches sent out by Lorenzo Stoakes for significantly speeding up kernel build times.
