It emphasizes the importance of test environments for safe experimentation, demonstrates diagnostic tools for investigating disk I/O, network bandwidth, and CPU usage, and illustrates resource management techniques for resolving performance bottlenecks in server systems. </p> <hr> <h2 id="beyond-reproduction-cases">Beyond Reproduction Cases</h2> <p>When first encountering debugging concepts, it may seem that having a reproduction case automatically reveals the root cause of the problem. However, this is frequently not the case. The reproduction case and root cause are distinct elements in the troubleshooting process.</p>
