Performance & Scalability Comparison
Pinecone Performance
Query Performance
Pinecone delivers consistently low latency with p50 latencies under 10ms and p99 under 50ms, even at billion-vector scale. The serverless architecture automatically optimizes query routing and caching.
Benchmark: 1M vectors, 768 dimensions
• Query latency: 8ms p50, 45ms p99
• Throughput: 5,000+ QPS
• Index time: Real-time (<1 second)
Scalability
Automatic scaling from zero to billions of vectors without configuration. Pod-based architecture allows independent scaling of storage and compute.
Weaviate Performance
Query Performance
Weaviate offers good performance with HNSW indexing, though latencies are typically higher than Pinecone. Performance varies based on deployment configuration and hardware.
Benchmark: 1M vectors, 768 dimensions
• Query latency: 25ms p50, 95ms p99
• Throughput: 2,000+ QPS
• Index time: 5-10 minutes
Scalability
Horizontal scaling through sharding and replication. Requires manual configuration and cluster management for large-scale deployments.
