"Linux is well tuned for throughput-limited applications, but it is not well designed for deterministic response, though enhancements to the kernel are available to help or guarantee determinism. So-called real-time applications require, among other things, deterministic response. In this article I examine the nature of real-time applications and Linux's strengths and weaknesses in supporting such applications. In later articles I will examine various approaches to help real-time applications satisfy hard real-time requirements. Most of these issues are with respect to the Linux kernel, but the GNU C library, for example, plays a part in some of this."
