What to Do When Qdrant Indexing Is Too Slow

Qdrant does NOT build HNSW indexes immediately. Small segments use brute-force until they exceed indexing_threshold_kb (default: 20 MB). Search during this window is slower by design, not a bug.

• Understand the indexing optimizer Indexing optimizer

Uploads/Ingestion Too Slow

Use when: upload or upsert API calls are slow. Identify bottleneck: client-side (network, batching) vs server-side (CPU, disk I/O)

For client-side, optimize batching and parallelism:

• Use batch upserts (64-256 points per request) Points API
• Use 2-4 parallel upload streams

For server-side, optimize Qdrant configuration and indexing strategy:
