Performance Tuning

Linux Kernel Version

  • Use the latest stable upstream Linux kernel for the best performance.

    • Despite claims of custom kernels providing enhanced performance, benchmarks show that in most cases they are still not as fast as the upstream Linux kernel. [1] The LTS Linux kernel is slower and does not support newer hardware compared to the latest stable version but it is more stable. [2]

  • Use at least Linux kernel 6.6 [3] to get the low latency benefits of the new EEVDF CPU scheduler. [4]
