It proves a lot of things I try to impress upon people who talk about how RDMA is such a "must have" because the software stack can't possibly give anything near HW latency. Obviously such arguments are complete bullshit as is shown by these changes. This is exactly the kind of approach that makes sense rather than trying to put entire TCP stacks in the network card firmware. Thanks again for doing this work and I look forward to applying this stuff once all the kinks are worked out. The folks in the Intel NIC group continue to impress me. ------------------------------------------------------------------------------ Everyone hates slow websites. So do we.
