Hi, As we know, RDMA support one-sided operation(i.e. write/read) and two-sided operation(i.e. send/receive), according to literature(e.t. pilaf, ATC'13), researchers claims that: one-sided operation perform better than two-sided operation both in throughput and latency, NICs can achieve 2.45 million write/read operations per second while 0.7… Show more

We have explored this in great detail in our research: FaSST: Fast, Scalable and Simple Distributed Transactions with Two-Sided (RDMA) Datagram RPCs | USENIX Design Guidelines for High Performance RDMA Systems | USENIX https://dl.acm.org/citation.cfm?id=2626299
