💡 Model Answer
A bottleneck is a component or resource that limits overall system performance. It could be CPU, memory, disk I/O, network bandwidth, or a slow database query. When one part becomes saturated, it throttles the entire system, causing increased response times or failures. Detecting bottlenecks involves monitoring resource utilization and correlating spikes with performance metrics.
