Polled I/O is often unsatisfactory because it relies on the CPU to continuously check the status of I/O devices, which can lead to inefficient CPU usage and increased power consumption. This polling mechanism can introduce latency, as the CPU may not immediately respond to incoming data or events. Additionally, it can create bottlenecks in systems with multiple I/O devices, where the CPU struggles to manage concurrent data streams effectively. Overall, this approach can hinder system performance, especially in high-throughput or real-time applications.
