Chapter 3: Using Engines and CPUs

Adaptive Server’s multithreaded architecture is designed for high performance in both uniprocessor and multiprocessor systems. This chapter describes how Adaptive Server uses engines and CPUs to fulfill client requests and manage internal operations. It introduces Adaptive Server’s use of CPU resources, describes the Adaptive Server Symmetric MultiProcessing (SMP) model, and illustrates task scheduling with a processing scenario.

This chapter also gives guidelines for multiprocessor application design and describes how to measure and tune CPU- and engine-related features.
