  • dperf

    Project mention: DPVS uses dperf for performance testing | dev.to | 2023-01-27

    Today, it was found that the DPVS project used dperf for performance testing, including bandwidth, CPS, concurrent connections and PPS. The test document of the DPVS project records the test environment, test methods, configurations, that makes a grate article. I put the link of this article on the dperf README. I'd like to say thanks to the authors of this article. and I suggests reading this article before using dperf for performance testing.
