I've tested iperf3 on this setup a few times—on the 1 Gbps port, I get 940 Mbps up, 940 Mbps down (doing `--reverse`), and `iozone` with a filesize of 10...

@ThomasKaiser - see above (https://github.com/geerlingguy/raspberry-pi-pcie-devices/issues/615#issuecomment-2035286025) — `SMB_CURR_SIGN_ALGORITHM AES_128_GMAC` does that mean it's enabled?

I tried adding `server signing = No` to the `smb.conf` on the Pi (and restarting it), and also tried disabling signing on the macOS side: ``` printf "[default]\nsigning_required=no\n" | sudo...
