AbstractThe aim of this work is to provide some insight into the responsetime statistics of enterprise resource planning systems. We propose a simple meanfield model for the responsetime distribution in such systems. This model yields a lognormal distribution of responsetimes. We present data from performance measurements to support the result. The data show that the responsetime distribution of a given transaction in a given system is generically a lognormal distribution or, in some situations, a sum of two or more lognormal distributions. Deviations of the lognormal form can often be traced back to performance problems in the system. Consequences for the interpretation of responsetime data and for service level agreements are discussed.
