Table 1 is looking specifically at getting a chunk of data off the wire and into the users code. Look at Table 2 for a comparison of redis read/write. Average time for a write is 163 μs - of which 137 μs is spent in fsync(2)
Right but you can't compare table 2 data to the network stack, table 2 data is only timing the redis operations. Which as stated take up significantly less time than the time spent in the network stack.
