Performance testing in enterprises includes gathering macro metrics like CPU utilization and response times. However, these metrics have limitations, such as failing to catch acute performance issues and complicating troubleshooting. Complementing macro metrics with micro metrics—focusing on memory, thread, and network activities—enhances visibility and aids in addressing performance problems effectively.
The Spring IOC Container currently builds all dependencies for a requested bean, leading to unnecessary memory and CPU usage due to unused objects. The proposed solution suggests implementing a lazy-loading feature for dependencies, allowing the container to create required objects dynamically during runtime, thereby optimizing resource utilization and performance.
