DaRPC registers only one memory region and creates single send and receive buffers (for post send and post receive) by using slices within this memory region (instead of creating a separate memory registration per send or receive buffer).
Advantages:
Higher locality when allocating a big block
Better for caching and TLB
Use less memory registration resources on the RDMA card
The change improves DaRPC IOPS in a 8 core server setup from
2.4Mio IOPS to 3.6Mio IOPS.
This is a first step in improving DaRPC performance.
