Adding Garbage Collection (GC) metrics to CI/CD pipelines helps improve software performance and avoid issues like OutOfMemoryError. Monitoring GC activity allows teams to spot memory problems early, improve response times, and reduce costs. This approach helps catch performance issues sooner, leading to smoother releases and more reliable software.
Java's Garbage Collection manages memory by clearing unused space. If the number of GC threads isn't set correctly, it can slow down your application. Balancing the thread count is key to preventing delays and memory issues, ensuring smooth performance.
The post discusses optimizing a Java application used for controlling warehouse robots, which faced performance issues due to long Garbage Collection (GC) pauses. By analyzing the GC log, it identified a large heap size and the CMS GC algorithm as culprits. Switching to the G1 GC algorithm reduced GC pauses significantly, enhancing application performance without major structural changes.
