This software is a performance profiling tool that is both free and open source. It allows users to identify and analyze the performance of applications or systems.
JStress provides various attack or run strategies that simulate different types of loads on the system, allowing users to execute tasks that generate a range of different loads. The results of these tests can be imported into various statistics tools or plotted. Since JStress is meant to be run from a remote shell, it doesn't have any GUI component, reducing its overhead.
JStress enables users to execute it from the same network as the target application. This feature allows users to increase the chance of saturating the system with requests, rendering a more accurate profile. Users can also run multiple instances of JStress concurrently on multiple machines. When analyzing the results, users need to merge the individual logs (sorted by time stamp) and enable one instance to step incrementally on the arrival rate while providing the others with a constant arrival rate.
One thing to note is that JStress is licensed and distributed under the terms of the IBM Public License. Overall, JStress is an efficient and useful tool for monitoring the performance of both simple and complex systems.
