Faster autoscaling for vLLM: Restoring from snapshots instead of starting cold
Cold-start latency is one of the biggest bottlenecks when scaling inference. Parasail's model snapshotting saves and restores CPU and GPU process state to bring vLLM replicas online 3-5x faster than rebuilding from scratch.
EngineeringMaking Cold Start Latencies go Brrrr: A Multi-pronged Approach (Part 1)
We walk through how we combined fastsafetensors, O_DIRECT, and io_uring to get fast cold-starts and fast warm-starts on the same stack.
