.We want to compare the performance of a single threaded disk server with a multithreaded 1. Suppose the server takes 25 ms to receive a request for work from client, dispatch the request for processing and actual data request processing when reqd. Data is in main memory. If the reqd. Data is not in the main memory a real disk operation is needed and an additional 75 ms are reqd. On the average. On the average 25% of the clients requests access the disk. During the disk I/O period the thread waits. Assume that there is no other process in system when the server is running. How many requests can the server handle per second if its a)single threaded b)multithreaded
