  "account": "In 2026, Linux kernel performance enhancements have led to an approximate 8% improvement in AMD EPYC server performance, based on measurements taken using an AMD EPYC 8635P Sorano server equipped with 84 Zen 5 cores, 6 x 64GB DDR5 memory, and a Kioxia KCD8XPUG1T92 PCIe Gen5 NVMe SSD. The comparison was made between Linux 6.18 LTS from the end of 2025 and the latest Linux 7.3 kernel, which is set to become the 2026 LTS kernel if released on schedule. The Linux 7.3 kernel, currently the most recent version for this assessment, was evaluated against Linux 6.18.52, both running on the same Ubuntu 26.04 LTS operating system.\n\nThe performance and power impact of the upstream Linux kernel improvements observed this year are attributed to a series of optimizations made over the course of 2026. These improvements, spanning various areas, have been particularly beneficial for I/O performance. The measurement was conducted using a collection of over 100 Linux server benchmarks, which provide insight into the evolution of Linux kernel performance from the LTS release of Linux 6.18 at the year's end to Linux 7.3, the current latest and greatest kernel. In the coming months, as the official 2026 LTS kernel is determined, additional benchmarks will be performed on more hardware to better assess the kernel performance improvements from one LTS release to the next.",
  "summary": "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…",
