A client makes remote procedure calls to a server. The client takes 5 milliseconds to compute the arguments for each request, and the server takes 10 milliseconds to process each request. The local operating system processing time for each send or receive operation is 0.5 milliseconds, and the network time to transmit each request or reply message is 3 milliseconds. Marshalling or unmarshalling takes 0.5 milliseconds per message.
Calculate the time taken by the client to generate and return from two requests: (i) if it is single-threaded, and (ii) if it has two threads that can make requests concurrently on a single processor. You can ignore context-switching times. Is there a need for asynchronous RPC if client and server processes are threaded?
