Boost Java Application Efficiency and Slash Costs with GraalVM and Spring AOT
summary
GraalVM + Spring AOT delivers faster startup and lower runtime memory than a HotSpot JIT JVM, at the cost of larger binaries and longer builds. Example data: build time ~10 minutes on 2 vCPU/4 GB, now ~2–6 minutes on 8–16 CPU and 16–32 GB, and Spring Boot fat jars remain ~40–60 MB versus trimmed native images. Demonstrated result: native exe Swing app streaming periodic screen snapshots over WebSocket (avoids WebRTC/RTMP) works in production tests and reduces OOM risk.
