VPP has been shown to run at 22.1 Mpps on a single core of Gracemont (the efficient / Atom core in Alder Lake), and 42.3 Mpps on 2 cores. (Intel E810 4x25 NIC, DPDK 22.0, VPP 22.06, GCC 9.4.0, RFC 2544 test with packet loss <= 0.1%. The same core will do 14.99Gbps of IPsec (aes-128-gcm, 1480 byte packets) using VPP, largely because it supports (VEX-encoded) VAES. While these aren't ARM cortex A72s, they're quite close (cheap low power) for Intel.
