Suppose that the time to do a null remote procedure call (RPC) (i.e., 0 data bytes) is 1.0 msec with an additional 1.5 msec for every 1K of data. How long does it take to read 32 K from the file server as 32 1K RPCs?

Option B

A single 32K RPC takes 1.5*32 + 1.0 = 49.0 msec

32 1K RPCs take 1.5*32 + 1.0*32 = 80.0 msec
