How to Reduce Spring Boot Memory Usage?
Spring Boot applications typically consume significant memory (150+ MB) due to JVM architecture, embedded server threads, and framework overhead. Memory usage can be reduced through JVM tuning (serial garbage collector, reduced thread stack size, RAM limits), configuring web server thread pools, container-aware deployment practices, and removing unused dependencies. Key techniques include using -XX:+UseSerialGC, -Xss512k for thread stacks, setting MaxRAM limits, reducing Tomcat threads to 20, and matching JVM flags to container limits.
