i did test it. in my setup we couldn't get IPsec to not drop a lotmof packages, so the benefits of aes-ni was lost in retries. switching that IPsec setup to chacha20-poly1305 actually made most of the drops go away.
I have no idea what was going on, but wireguard and IPsec was comparable in that test, with ispec being sliiiightly faster. the network has almost no latency, so if the retries remain on slower networks, that would change.
