Even if this is faster than Samba... the max. transfer speed will be dictated by the client running Windows, surely.

- londons_explore 3y agoRDMA tends to run at 100 Gbps rates and microseconds of latency. In many cases, a data transfer can occur without the CPU running much OS code at all - it's all done by the network hardware DMA'ing the right memory from one machine, across the network, and into the right place in RAM of another machine. It is often faster than reading from local SSD. One datacenter use is to find another machine on the network who already has a file you want to load to RAM, and loading that file across the network from them rather than reading the file from your local SSD, simply because it is faster to do so.
