This work is latency critical, because volume IO is blocked until it is complete. Larger cells have better tolerance of tail latency (e.g. Studies across three decades have found that software, operations, and scale drive downtime in systems designed to tolerate hardware faults. Cells have seven nodes.

Each of the two vector units can issue one FMA instruction per cycle, assuming that there are enough independent accumulators to tolerate the 6-cycle dependent-operation latency. This is an uninspiring fraction of peak performance that would normally suggest significant inefficiencies in either the hardware or software.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).
