Qdrant Performance: Benchmarks, Latency & Limits 2026

Qdrant hits ~12ms p99 at 10M vectors and up to 4x the RPS of open-source rivals. Binary quantization cuts memory 32x. Multi-AZ cloud carries a 99.95% SLA.

Qdrant Performance verdict

Verified today·7 sources checked

Qdrant delivers about 12ms p99 at 10M vectors, and up to 4x the RPS of leading open-source alternatives.

Binary quantization cuts memory 32x with a 40x search speedup. Multi-AZ cloud carries a contractual 99.95% SLA.

How to size it

Pick Qdrant for self-hosted or hybrid-cloud RAG workloads where you want the lowest open-source p99 latency, aggressive quantization compression, and no per-namespace throughput cap. Budget for cluster sizing, since throughput scales with nodes, not a managed dial.

Honest limits
  • The benchmark latency numbers are a mix of vendor-published figures and independent analyses, with no fully independent third-party audit.
  • Self-hosted throughput scales with node count. There is no per-namespace cap, unlike Pinecone, but you own cluster sizing.
  • Binary quantization works best for embeddings with 1024 or more dimensions, and performance degrades below that threshold.

Reliability and distributed architecture

  • Raft consensus protocol maintains cluster topology and collection structure across all nodes
  • write_consistency_factor sets how many replicas must ack a write; defaults to 1, max equals replication_factor
  • Cluster continues accepting updates if at least one replica per shard is online (default write_consistency_factor=1)
  • Raft quorum recovery requires more than 50 percent of nodes to be healthy
  • Multi-AZ Premium clusters carry a contractual 99.95 percent uptime SLA
  • Standard cloud tier SLA is 99.5 percent; Premium single-zone is 99.9 percent
  • Zero-downtime upgrades and automated backups are included in all managed cloud tiers

Benchmarked results vs peers

  • On its own benchmark suite Qdrant reports the highest RPS and lowest latencies in almost all scenarios against Weaviate, Milvus, Elasticsearch and Redis
  • It delivers up to 4x the requests per second of competitors on a 1M OpenAI-vector dataset
  • An independent 2026 analysis measured ~12ms p99 latency at 10M vectors, ahead of Weaviate (~16ms) and Milvus (~18ms)
  • The same independent test recorded 48% lower p99 than Postgres with pgvector and pgvectorscale (38.71ms vs 74.60ms)
  • Against Elasticsearch it indexes roughly 10x faster, 32 minutes versus 5.5 hours for 10M vectors
  • Benchmarks ran on an 8 vCPU / 32GB server against an 8 vCPU / 16GB client with a 25GB per-engine memory ceiling

Qdrant Performance FAQ

What is Qdrant's query latency at scale?

About 12ms p99 on a 10M-vector dataset, which is 25 to 33% faster than Weaviate, at around 16ms, and Milvus, at around 18ms, on the same workload, per a 2026 independent comparison.

What throughput can Qdrant handle?

Up to 4x higher RPS than competitors on some datasets, in Qdrant's own benchmarks. Unlike SaaS products, there is no hard per-namespace cap. Throughput scales with the number of cluster nodes you provision.

How much does binary quantization speed up search?

Up to 40x search speedup versus full float32 vectors, with a 32x memory reduction. Recall stays at 0.98 or higher for 1536-dimensional models like OpenAI ada-002 with 3 to 4x oversampling, but degrades below 1024 dimensions.

What SLA does Qdrant cloud offer?

The standard cloud tier is 99.5% uptime. Premium single-zone is 99.9%. Premium Multi-AZ is 99.95%, the highest tier with a contractual guarantee.

How does Qdrant handle node failures in a cluster?

It uses Raft consensus for cluster topology. If fewer nodes fail than the replication factor, reads and writes continue. Recovery requires more than 50% of nodes to be healthy. Setting write_consistency_factor to match the replication factor blocks writes when a replica is offline, which prevents divergence.
