In 2019, Ostinato tested an Intel XL710 40G NIC using DPDK. Today, Ostinato Turbo handles 10/25/40/100G line-rate using AF_XDP - no DPDK needed.

Running Ostinato Turbo on cloud VMs? Size the instance by max packets/sec: MaxPps = MaxBitRate / 8 / (MinPktSize + 20). A 10Gbps test at 64-byte packets needs ~15 Mpps.
