Claim One:
1. A method, in an information handling system comprising one or more processors and a memory, of predicting system performance, the method comprising: identifying a Queuing Network Model (QNM) corresponding to clustered system that handles a plurality of service demands using a plurality of parallel server nodes that process a workload for a quantity of users; receiving a workload description that includes server demand data; predicting a performance of the clustered system, wherein the predicting further comprises: transforming the QNM to a linear model by serializing the parallel services as sequential services; identifying transaction groups corresponding to each of the server nodes; and distributing the workload among the transaction groups across the plurality of nodes; and analytically solving the linear model, wherein the solving results in a predicted resource utilization (RU) and a predicted response time (RT).
