When you're doing packet capture that normally costs one system call per packet, Netmap/DPDK/PF_RING are a clear win. But with TCP a single system call can send or receive many packets and TSO/LRO offloads help even more. I haven't seen any numbers about the benefits of kernel bypass for TCP; maybe SolarFlare has some.

I was about to point out solarflare's openonload. Its only compatible with an sfc nic though. With onload, i've seen about a 20% throughput increase when turning onload on.
