Projects / uperf


uperf is a network performance tool that supports modelling and replay of various networking patterns. It represents the next generation benchmarking tools (like filebench) where instead of running a fixed benchmark or workload, a description (or model) of the workload is provided and the tool generates the load according to the model. By distilling the benchmark or workload into a model, you can do various things like change the scale of the workload, change different parameters, change protocols, etc and analyse the effect of these changes on your model. You can also study the effect of interleaving CPU activity, or think times or the use of SSL instead of TCP, among many other things.
