alt Hacker NewsHow is IPSec performance better than wg? I never heard this before, it sounds intriguing.

If you have an edge device which implements hardware IPsec at 10g+ but pushes WireGuard to software on an underpowered cpu then sure.

At this time, there is no commercial offering for hardware/ASIC WireGuard implementations. The standard WireGuard implementation cannot reach 10G.
The fastest I am aware of is VPP (open-source) & Intel QAT [1], which while it is achieves impressive numbers for large packets (70Gbps @ 512 / 200Gbps @ 1420 on a $20k+ MSRP server), is still not comparable with commercial IPsec offerings [2][3][4] that can achieve 800Gbps+ on a single gateway (and come with the added benefit of relying on a commercial product with support).
