It does not. If this was the case, round trip wire to wire latency below 1.0-1.2 microseconds in software would’ve been impossible. But it clearly is possible -

- nly 9mo agoYou mean like this one directly from AMD showing a median 1/2 RTT ef_vi latency of 590ns (for UDP)? Using their latency generation card that came out just a few months ago? https://docs.amd.com/r/en-US/ug1586-onload-user/Latency-Test-Results?tocId=b01e6F1uBlNm4SuDiN1cSQ https://docs.amd.com/r/en-US/ug1586-onload-user/Latency-Test...
