How much of this is achievable depends on the end-to-end link capacity and background network traffic at the time. Also, you might need some CPU pinning and NUMA tuning to achieve high throughput in iperf tests, see example: https://github.com/fabric-testbed/jupyter-examples/blob/main/fabric_examples/complex_recipes/iPerf3/iperf3_optimized_smart_nic.ipynb Like Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
