BENEFITS OF THREADS OVER PROCESS
If implemented correctly after those threads have some advantages of (multi) processes, they take:
1. Less time to create a new thread than a process, for the reason that the newly created thread uses the current process address space.
2. Less time to finish a thread than a process.
3. Less time to switch among two threads within the same process, partly for the reason that the newly created thread uses the current process address space.
4. Less communication expenses communicating between the threads of one process is easy because the threads share everything address space in particular. Consequently, data produced by one thread is right away available to all the other threads.
