HALVING NODE.JS MEMORY USAGE

Summary from the TLDR Dev newsletter

Platformatic figured out how to cut Node.js memory usage in half by enabling V8's pointer compression, a feature that shrinks internal pointers from 64 to 32 bits. It required zero code changes and just a Docker image swap. Their AWS benchmarks showed 50% less memory with only ~2.5% latency overhead, and P99 latency improved because garbage collection had less work to do.
