Software System Performance and Reliability

In this paper, we describe a general-purpose timing and tracing package, called CASPER, for UNIX® System V. We also present the results of a study of the behavior of the UNIX System V fork system call using this package. CASPER is designed to support high-resolution timing and tracing of software under UNIX System V. With CASPER, we were able to obtain detailed and accurate information on the behavior of the fork system call, which led to minor algorithmic changes that reduced the time to execute small forks by about 15 percent.
