performance on a multiprocessor system than a single processor system? Explain. Answer: A multithreaded system comprising of multiple user-level threads cannot make use of the different processors in a multiprocessor system simultaneously. The operating system sees only a single process and will not schedule the different threads of the process on separate processors. Consequently‚ there is no performance benefit associated with executing multiple user-level threads on a multiprocessor system.
