Eliminating the Garbage Collector: How Inferred Memory Slots Achieve <2ms Cold Start
Runtime garbage collectors introduce stop-the-world latency spikes, non-deterministic memory footprints, and heavy runtime binary overhead (often 30MB+). In this dispatch, we break down how the Enlangg compiler builds a compile-time lifetime graph, allocating fixed memory slots in the stack data segment with zero background collector threads.
| Runtime Engine | Cold Start Latency | Base Memory RSS | GC Latency Spike |
|---|---|---|---|
| Enlangg (Slot Memory) | 1.4 ms | 1.2 MB | 0.00 ms (Zero Collector) |
| Node.js 22 (Google V8) | 42.1 ms | 34.2 MB | 4.5 - 28.0 ms |
| Python 3.12 (CPython) | 28.6 ms | 14.8 MB | 1.2 - 8.4 ms |
