在两台生产超级计算机上对三种 SOTA 向量数据库进行大规模评估，扩展至 64 个计算节点上的 256 个分布式 worker，结果显示：工作负载特性可能限制延迟下降，增加核心反而会降低查询吞吐，且从 16 扩展至 256 个 worker 仅带来 5.46 倍的性能提升。A large-scale evaluation of three state-of-the-art vector databases on two production supercomputers, scaling to 256 distributed workers across 64 compute nodes, reveals that workload characteristics can limit latency reduction, additional cores can reduce query throughput, and scaling from 16 to 256 workers only yields a 5.46x improvement.
