Good numbers either way, but you again much more limited hardware support since the drivers need to be DPDK specific.
- gonzo 5y agoYou can also run VPP over AF_PACKET (slower, but faster than the kernel) of AF_XDP (almost as fast as DPDK interrupt mode.) But Wireguard is still crypto-limited, the AES-GCM result proves it.
- SigmundA 5y agoWireguard isn't doing to bad considering its not hardware accelerated like AES-GCM. Also looks like AF_PACKET and AF_XDP are basically an alternative to DPDK with similar functionality but built into the kernel using kernel drivers, new to me.
