A client makes RMIs to a server. The client takes 5 ms to compute the arguments for each request, and the server takes 10ms to process each request. The local OS processing time for each send or receive operation is 0.5 ms, and the network time to transmit each request or reply message is 3 ms. Marshalling or unmarshalling takes 0.5 ms per message.
Estimate the time taken by the client to generate and return from 2 requests (i) if it is single-threaded, and (ii) if it has two threads which can make requests concurrently on a single processor. Is there a need for asynchronous RMI if processes are multi-threaded?
