Developer Daniel Lockyer shares a Cloud Run optimization: p99 container startup latency dropped 63%, with the monitoring graph falling from 20-40s to under 5s. The service scales up and down by 3,300 instances per day, which he estimates saves about 19 hours of compute time daily. For elastically scaled serverless workloads, cold-start latency drives both user experience and cost, making this a notable win on both fronts.
