    I've set up Pi2s3s4s as 'servers' before, it was
    never THIS complex however. A PI is just a very
    small Linux box. Alas if you need multiple net
    ports you may need to think of USB dongles.

    What he describes is the normal way to set up bridging between multiple
    network devices (in this case ethernet and wifi) under Linux. A WIFI access point usually works as a bridge, so this *is* required.

    Net/USB/WiFi speed ratings for PIs are almost always
    "best case" ... actually they're kinda LIES. The P4
    was much better, P5s even better, but it's not gonna
    be like a PCI card plugged into your Big Box.

    Also, there is a difference between "client" WIFI chips and "accespoint"
    wifi chips, regarding features and performance. Most client cards nowadays
    have some kind of limited access point mode, but is limited compared to a
    real access point (number of streams, number of simultaneous client and
    other WIFI features).

    I believe the raspberry pi wifi devices are more in the "client" category.

    However, while the observed performance may be due to hardware limits, I
    would expect better stability with only one client attached.

    - inbound traffic to the host is heavy.

    I get between 48% and 988% packet loss to external machines on the
    Internet. Mostly OK access to the rest of the LAN using the Wi-Fi interface.

    Could this be caused by WIFI power management? You might try disabling that.

    iw wlan0 set power_save off

    already done.
