Abstract

Extensibility can be based on cross-address-space communication or on grafting application-specific modules into the operating system. For comparing both approaches, we need to explore the best achievable performance in both models. This paper reports the achieved performance of cross-address-space communication for the L4 \mu-kernel on Intel Pentium, Mips R4600 and DEC Alpha. The direct costs range from 45 cycles (alpha) to 121 cycles (Pentium). Since only 2.3% of the L1 cache are required (Pentium), the average indirect costs are not to be expected much higher.
