IBM - Application Workload Modeler

A workload tool for determining server and network performance

IBM Application Workload Modeler is a tool for determining performance of servers and network infrastructure by modeling application traffic.

Helps you to allocate existing system resources more efficiently by modeling, by generating real traffic on your network, and by evaluating the network performance of existing workloads.
Lets you effectively plan additional system resources by analyzing performance impacts of new functions and/or increased capacity before they are deployed.
Benchmarks existing workloads, allowing you to measure the impact of new hardware or software.
Keeps your network and applications running efficiently and effectively by continuing to evaluate their performance over time or at different times of day.
