Accept() scalability on Linux

Steve Molloy, University of Michigan; Chuck Lever, Sun-Netscape Alliance

Abstract

This report explores the possible effects of a "thundering herd" problem associated with the Linux implementation of the POSIX accept() system call. We discuss the nature of the problem and how it may affect the scalability of the Linux kernel. In addition, we identify candidate solutions and considerations to keep in mind. Finally, we present a solution and benchmark it, giving a description of the benchmark methodology and the results of the benchmark.
