Fabric Performance Modeler

Welcome to the Fabric Performance Modeler

This tool helps you estimate capacity needs by simulating user workloads against Fabric SKUs. It models key Fabric behaviors like bursting, smoothing, and throttling to provide a realistic performance forecast. Start by defining your user demand and workload mix, then analyze the simulation results to select the right capacity.
