It should get close to 1 GB/s where 1GbE is limited to about 125 MB/s. Lower latency? Probably since most Ethernet drivers set interrupt coalescing by default. Intel e1000 driver, for example, have a cluster mode that reduces (or turns off) interrupt coalescing. I don't know if ceph is latency sensitive or not. > > Sorry, I meant 10GbE. 10GbE should get close to 1.2 GB/s compared to 1 GB/s for IB SDR. Latency again depends on the Ethernet driver.
