[libfabric-users] dpdk mlx5drv vs. openfabric

[Shane Miller]

Consider a Mellanox ConnectX5 NIC on Linux bare metal Xeon E-2378G 64Gb RAM. This configuration uses the mlx5 driver. DPDK can move ethernet UDP packets well under 1us each. Openfabric and libverb's perftest seems to plateau around ~1.5 us/ea. Mlx5 can be a more performant than 100% classic ibverbs pass through by directly accessing hardware.

I'm new here. Is there some perspective out there on openfabric v. DPDK w.r.t. to performance and goals for its future?
