Yes. But VPP also supports Wireguard, and when doing apple-to-apple comparisons, the performance difference between Wireguard vs IPsec AES-256-GCM is close to 2x. See https://fosdem.org/2021/schedule/event/sdn_calicovpp/attachm... slides 23 and 26: 5Gbps of Wireguard vs 9.5Gbps of IPsec.

And the main reason is the cipher: one is hw-assisted (AES-NI on x86), the other is not.

Again, I do think Wireguard is nice because it is a clean sheet design with good choices and it "just works". However when I hear "Wireguard is faster than IPsec" it is not true in my experience, and can be easily explain by the cipher choice.
