StarWind rPerf

Value Proposition

For system administrators looking to get the precise information on RDMA connections performance in their IT infrastructure, StarWind introduces Performance Benchmarking Tool (StarWind rPerf) – free RDMA link benchmarking tool. The utility measures both latency and bandwidth for RDMA connections between different operating systems such as Windows and Linux. No more need to maintain dozens of tools to find out the RDMA link performance and latency. StarWind rPerf is a single tool that does all the job.

StarWind rPerf is a single tool to measure both latency and bandwidth between Windows and Linux


Typical solutions lack the functionality to measure latency and bandwidth for RDMA connections between different operating systems, forcing users to install and configure multiple tools and perform segregated narrow focused tests. From this point, StarWind rPerf measures both latency and bandwidth for cross-platform RDMA connections.



StarWind rPerf is the only tool to properly measure Windows – Linux RDMA link bandwidth and latency.

Easy to use

No more need to combine and learn various tools to measure the RDMA link speed. One tool and few simple commands get the job done.


One tool provides all the necessary information you require, minimizing your time spent on diagnostics and benchmarks.
