The following measurements were recorded on AMD Turin Zen5 servers. The specification of the test systems is as follows:
- Super Micro AS -2015HS-TNR servers equipped with AMD Turin Zen5 - EPYC 9575F processor, 64 core, 3.3 GHz - 5GHz (Boost), 384 GB RAM.
- Custom BIOS version 5.35 (pre-release) configured for low latency, see BIOS Settings.
- AMD Solarflare X4542 Ethernet adapter (bundle 1.0.3.2 and bootloader 1.0.17.0).
- Direct attach cable linking the NICs:
- 10 Gb cable for measurements at 10 Gb
- Ubuntu 25.04 (x86_64 kernel, version 6.14-23).
- OS configured with AMDLL profile.
- Release candidate version of Onload (https://github.com/Xilinx-CNS/onload/commit/0395821bb0685a3019018b3a9b45c4f30915146f).
- sfnettest version 1.6.0.
It is expected that similar results will be achieved on any AMD based, PCIe Gen 5 server or compatible system.
