A ‘null’ RMI that takes no parameters, calls an empty procedure and returns no values delays the
caller for 2. 0 milliseconds. Explain what contributes to this time.
In the same RMI system, each 1K of user data adds an extra 1. 5 milliseconds. A client wishes to fetch 32K of
data from a file server. Should it use one 32K RMI or 32 1K RMIs?
What will be an ideal response?
Page 236 details the costs that make up the delay of a null RMI.
one 32K RMI: total delay is 2 + 32*1. 5 = 50 ms.
32 1K RMIs: total delay is 32(2+1.5) = 112 ms -- one RMI is much cheaper.
