It explains how operating systems manage processes, demonstrates techniques for splitting work across multiple processes and threads, distinguishes between I/O-bound and CPU-bound operations, and provides guidance on balancing parallelism to maximize throughput without overwhelming system resources. </p> <hr> <h2 id="the-problem-with-blocking-io-operations">The Problem with Blocking I/O Operations</h2> <h3 id="understanding-blocked-execution">Understanding Blocked Execution</h3> <p>Reading information from disk or transferring data over the network is a slow operation. In typical scripts, while this operation is ongoing, nothing else happens. The script is blocked, waiting for input or output while the CPU sits idle.</p>
