Performance Comparison of UUID vs Auto-Increment IDs in MySQL

Benchmarking three MySQL tables—auto_increment, UUID, and random long keys—shows that sequential auto_increment inserts are fastest, random keys are slower, and UUIDs dramatically lag due to random I/O and fragmentation, so use auto_increment for most workloads and reserve UUIDs only for required global uniqueness.
