VTRACE and Communication Performance Analysis

Peng Dai and Thomas W. Doeppner Jr.

November 1995


As the requirements for communication performance grow and the vast variation and improvement in hardware components increase, the various functionally different software layers have been increasingly responsible for performance degradation. In this paper, we explore the use of VTRACE, a tracing facility provided in Solaris, as a general methodology in communication per formance analysis and also present performance data for an experimental version of Sun's Solaris Operating System.
