When deploying Ruby applications (version 3.0+) to memory-constrained environments with low request volume, the goal is to minimize the Resident Set Size (RSS) to reduce infrastructure costs. While Ruby's Generational Garbage Collection (RGenGC) manages object lifecycles, the default heap expansion behavior can lead to a memory footprint that exceeds the act
