# JDK 25 optimized for RESTHeart: low-latency REST API, 1-2 vCPU, 1-2GB container RAM
# Default G1 GC is the best fit: MongoDB is the bottleneck, not the JVM.
# ZGC would add CPU and memory overhead with no benefit when virtual threads
# are mostly parked on I/O. G1 pause times are short enough at 1-2GB heaps.
# NOTE: Graal JIT is enabled by default to support GraalVM polyglot plugin capabilities.
# If you are not using polyglot plugins, adding -XX:-UseJVMCICompiler will reduce
# compiler memory overhead significantly in constrained containers (recommended for <512Mi heap).
