    Answer: None. Currently, we speak about 10Gbps as developed, and 25Gbps and 40Gbps as future technologies.

    Not sure I can only squeeze 120GB/s ish from my Win 11 i7 12th gen machine using iperf3 (no lan cable involved)

    In one powershell window open iperf3 folder and run
    Code:
    .\iperf3 -s
    
    Duplicate the tab and run
    Code:
     .\iperf3 -c 127.0.0.1 -P 26 | Select-String "^\[ ID\]" , "^\[SUM\].*sender" , "^\[SUM\].*receiver"
    
    [ ID] Interval           Transfer     Bitrate
    [SUM]   0.00-10.02  sec   140 GBytes   120 Gbits/sec                  sender
    [SUM]   0.00-10.02  sec   140 GBytes   120 Gbits/sec                  receiver
    10.109s
    
    Strange to me that WSL Ubuntu 24 are faster on the same machine

    Code:
    iperf3 -c 127.0.0.1 -P 26 | grep -E "^\[ ID\]|^\[SUM\].*sender|^\[SUM\].*receiver"
    
    [ ID] Interval           Transfer     Bitrate         Retr
    [SUM]   0.00-10.00  sec   248 GBytes   213 Gbits/sec  1845             sender
    [SUM]   0.00-10.01  sec   248 GBytes   213 Gbits/sec                  receiver
    
    I call the above stupid iperf tests

    Note: I think its my ram that is the bottle neck
