Performance

RTI Connext provides a significant performance advantage over most other messaging and integration middleware on every supported platform.

RTI-Placeholder

The Connext Advantage
High Throughput

Approaching the theoretical bandwidth of Gigabit Ethernet, using modest CPUs

Ultra-Low Latency

Increases linearly with data payload size

Reliability

Sustains low latency and throughput even at high levels of message traffic

RTI Connext Performance Benchmarks

RTI benchmarked Connext with a wide variety of latency and throughput tests using RTI Performance Test (PerfTest). It includes scripts to run the tests on different platforms.

These results show that Connext provides sub-millisecond latency that scales linearly with data payload size and throughput that easily exceeds 90% of line rate over gigabit Ethernet.

The PerfTest benchmarking tool is completely free, along with documentation and a video tutorial.

To run these benchmarks on your own hardware, please download or contact your local RTI representative:
