Abstract:
1. A method for modeling performance of an information technology system having a server for serving a class of transactions, the method comprising: modeling a service time for servicing transactions of the class on the server as one of a polynomial, exponential, or logarithmic function that comprises a first term including an average arrival rate of transactions of the class at the server raised to a first power and a second term including the average arrival rate raised to a second power higher than the first to generate a service time function; modeling a processor overhead time of a processor of the server as one of a polynomial, exponential, or logarithmic function that comprises a third term including the average arrival rate and a fourth term including the average arrival rate raised to a fourth power higher than the third to generate a processor overhead function; optimizing coefficients of the terms of the service time function and coefficients of the terms of the processor overhead function; and generating a performance model of the information technology system using the resulting service time and processor overhead functions.
