COMPARATIVE PERFORMANCE MODELING FOR DISTRIBUTED OBJECT ORIENTED APPLICATIONS

摘要

A performance modeling tool and method permitting the user to define the elements of a distributed system (hosts, networks and response times), and e xamine the effect on performance of different distributions of application processe s over the system at an early stage in application design. Once a user has defined a pe rformance scenario, it is saved to a data model as a number of interdependent persiste nt objects that show the distribution of the application for a particular performance s cenario from different views. Multiple alternates of each object can be stored. The user can construct different performance scenarios for analysis from the stored objec ts. Analysis can include performance simulation from which the user can obtain performance projections for an application process or several application pr ocesses over different distributions of the performance workload.
