A Hacker News discussion highlights WireGuard's superior speed and connection reliability compared to OpenVPN, especially on lower-end hardware. Users report 3-5x faster throughput on routers running OpenWRT and Mikrotik. One user emphasizes WireGuard's ability to handle roaming without interrupting active connections, a feature not always reliable with other VPN solutions. While some point out alternatives like Tinc offer advanced features such as mesh routing and layer 2 VPN, the overall consensus favors WireGuard for its efficiency and ease of use. Performance benchmarks show modern CPUs can easily handle the encryption workload, suggesting the network is often the bottleneck, rather than processing power. One user proposes a cost-effective 10GbE testing setup using used components.
