WireGuard: 1Gbps Network Saturation Achieved

The author previously assumed encryption was too slow to achieve network saturation, even on Gigabit Ethernet. However, recent testing revealed WireGuard, running on readily available servers (Xeon E-2226G), readily saturated a 1Gbps network without special tuning, exhibiting low CPU usage. This challenged the author's assumptions about encryption speed, suggesting many methods could theoretically saturate a 1Gbps link, and highlighting potential performance tuning needs for existing VPN servers.
