Memory Latency

Another issue affecting performance is, of course, the latency: how long (in terms of cycles) does it actually take to transfer the information after we make a request? In Table 3, we list the memory latency for seven machines. We can see that the time ranges from 14 to 50 cycles. Obviously, a memory latency of 50 cycles is going to impact the algorithm's performance.
