The hilarity is that most business environments could benefit from the same networking "tricks" used by HPC, but don't bother to set any of it up.
I've even seen a few places that have even purchased the prerequisite hardware but then never turned the features on.
Things like hardware flow control, cut-through switching, jumbo frames, SR-IOV, RDMA, etc... are just a few checkboxes away and can give even small VMs crazy good bandwidth and latency.
