You can toggle it without needing the BIOS. It is possible to disable SMT from grub, with Linux kernel boot arguments. It even seems possible to disable/enable it without a reboot. See https://www.golinuxhub.com/2018/01/how-to-disable-or-enable-hyper.html > My WAN is 'only' 400Mbps anyway so > hardly a taxing test.

Set up a separate WG network with a peer on your Gbit LAN. Or even run a virtual machine on the same host, and run WG between host and VM, which should get you multi-Gbit raw throughput and likely make WG encryption the bottleneck. That way you can observe not only the CPU load, but also the transfer speed reached changing with HT on/off. -- With respect, Roman _______________________________________________ WireGuard mailing list WireGuard@lists.zx2c4.com https://lists.zx2c4.com/mailman/listinfo/wireguard
