Throughput Benchmark ==================== The throughput is measured between two identical machines using the test configuration shown below and running the |rti_rtiperftest|_ tool. The test environment is: - x86_64 CentOS Linux release 7.1.1503 - RTI Perftest 3.0 - Switch Configuration: D-Link DXS-3350 SR: - 176Gbps Switching Capacity - Dual 10-Gig stacking ports and optional 10-Gig uplinks - Stacks up to 8 units per stack - 4MB (Packet Buffer Size) - 48 x 10/100/1000BASE-T ports - Machine: - Intel I350 Gigabit NIC - Intel Core i7 CPU: - 12MB cache - 6 Cores (12 threads) - 3.33 GHz CPU speed - 12GB memory :: +-----------+ +----------+ | | | | | Sender +----------Sample --------->| Receiver | | | | | +-----------+ +----------+ Interpretation of the measurements: - Length - The size of the DDS sample payload (UDP overhead is _not_ included) - Packets - The number of samples written. - Packets/sec - The number of samples written per second. - Mbps - The bandwidth utilization for the payload based on Size and Packets/sec. - Lost - On the subscriber size the number of packets received is counted against what is expected. - % - Lost packets measured in percent.
