    Configuring lowest latency kernel

  • Original language description

    Linux kernel performance is a key parameter for many applications and tuning the kernel for optimal performance can be a challenging task. One reason is that there are many knobs one can use to tweak the performance. One such knob is compile-time con?guration of the Linux kernel and in this paper, we are interested in how this con?guration in?uences system response-time (latency), which is an important parameter for real-time applications. We developed a tool that uses a SAT solver to systematically generate valid kernel con?gurations. For each con?guration (typically, we haveseveral thousands con?gurations) the kernel is compiled, booted and a set of benchmarks is executed. The benchmark results are processed and we try to calculate the contribution of individual con?guration options to the benchmark results. The benchmark used in this paper is the well-known cyclictest utility and we investigate the e?ect of 54 con?guration options to its results. This is still work in progress and t
