Event Loop Lag: Why CPU Usage Is a Liar

1. 1Analyze CPU usage patterns to identify potential bottlenecks
2. 2Use profiling tools to measure event loop lag
3. 3Configure and run benchmarks to simulate real-world workloads
4. 4Test and optimize code to reduce event loop lag
5. 5Monitor and adjust application performance in production

Software engineers and DevOps teams benefit from understanding event loop lag to optimize application performance and reduce latency

💡 Event loop lag can be a major bottleneck in Node.js and JavaScript applications, even if CPU usage appears low

💡 Don't trust CPU usage alone to find bottlenecks in Node.js and JavaScript apps. Look for event loop lag instead!
