With the in-development Linux 7.3 kernel showing some nice performance improvements over Linux 7.2 in different areas, Linux 7.2 also having brought some nice gains especially for I/O, and the preceding kernels also having seen some nice performance optimizations this year, I wanted to measure how far the Linux kernel performance has evolved so far in 2026. Today's article is looking at that with how the Linux kernel performance has evolved since the Linux 6.18 LTS kernel at the end of 2025 to the current Linux 7.3 kernel.
