Each process runs on its own CPU, but when several of them are running each takes a little longer because they contend for the slow main memory, even though each process has a CPU all to itself. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.rutgers.edu | ||||||||||||
