V8 Snapshot Trade-off: Embedded Code Objects vs. Lazy Recompilation for Cold-Start Latency
When building a V8 embedder that targets sub-50 ms cold-start on constrained devices, the snapshot strategy becomes a primary lever. Including compiled code objects in the heap snapshot eliminates JIT compilation pauses during the first few hundred milliseconds of execution, but inflates the serialized blob by roughly 30–50 percent and ties the artifact to a
