The impact of operating system structure on memory system performance
1993
ACM SIGOPS Operating Systems Review
In this paper we evaluate the memory system behavior of two distinctly different implementations of the UNIX operating system: DEC's Ultrix, a monolithic system, and Mach 3.0 with CMU's UNIX server, a microkernel-based system. In our evaluation we use combined system and user memory reference traces of thirteen industry-standard workloads. We show that the microkernel-based system executes substantially more non-idle system instructions for an equivalent workload than the monolithic system.
