How has memory consumption changed? Did you have to configure anything?

Memory consumption in Java applications can vary depending on load, new features, or code changes. When memory usage increases, JVM parameters often need to be adjusted, such as:

• Heap size via -Xms and -Xmx.
• Garbage collector (GC) settings, for example, choosing between G1, CMS, or ZGC.
• Metaspace configuration (-XX:MetaspaceSize, -XX:MaxMetaspaceSize).

To analyze memory usage, profiling tools (VisualVM, YourKit) and monitoring (JMX) are useful. They help identify memory leaks or inefficient code sections. For example, if the application starts garbage collecting more frequently and slowing down, it’s worth checking whether the number of created objects has increased and optimizing their creation.
