Abstract

UNIX is one of the most widely used operating systems on current workstations. However, UNIX was originally designed as a multitasking and time-sharing system with little concern for supporting real-time applications. Recent versions of UNIX have incorporated real-time features and the designers of these systems claim to provide better response times than the standard UNIX kernel. In order to assess the benefits of these new features and verify these claims, this paper compares the real-time performances of two popular versions of UNIX namely System V Release 4.0 and System V Release 4.2 for the Intel platform.
