I agree with you that requests/second is not the only or more sensible parameter to meter performances, this is because redis-benchmark reports latency percentile too. I just suppressed the output in the example, but it looks like this: ====== SET ====== 10008 requests completed in 0.39 seconds 50 parallel clients 3 bytes payload keep alive: 1 1.03% <= 0 milliseconds 38.83% <= 1 milliseconds 73.12% <= 2 milliseconds 95.34% <= 3 milliseconds 97.93% <= 4 milliseconds 99.50% <= 5 milliseconds 99.75% <= 7 milliseconds 99.84% <= 8 milliseconds 99.93% <= 9 milliseconds 99.94% <= 10 milliseconds 100.00% <= 11 milliseconds 25401.02 requests per second As you can see under this load most clients are served in 4 milliseconds or less, including both the transmission of the request and the reception of the full reply.
