Out-Of-The-Box 10GbE Network Benchmarks On Nine Linux Distributions Plus FreeBSD 12

In iPerf3's TCP testing, FreeBSD 12.0 did successfully offer better performance than all of the Linux distributions benchmarked.

When increasing the number of iPerf tests running in parallel for the TCP run, FreeBSD 12.0 was coming in line with most Linux distributions while Clear Linux and Ubuntu 18.10 were falling behind the rest.

In the Nuttcp benchmark, FreeBSD 12.0 secured another win in this out-of-the-box 10GbE network performance testing using the HP QLogic adapter.

Under Netperf, Clear Linux was back to performing competitively on this dual Xeon Tyan server and in the TDP/UCP request response tests it was a race between Clear Linux and FreeBSD.

Those are the results for the out-of-the-box Linux/FreeBSD networking performance on this particular server with QLogic 10GbE networking adapter. Of course, from the small hardware set used for testing it's not practical drawing any widespread conclusion, so take these results as you wish. Coming up will be some additional tests including Windows Server and using different networking hardware to see how the performance compares, as well as looking at the benefits of some tuning/tweaking for better Linux networking performance. Via the Phoronix Test Suite you can also run these same open-source network benchmarks in the same manner across your networking hardware for comparison purposes.
