## Key Findings

### Short-term Memory (SQLite)

- Single INSERT operations are extremely fast (<0.5ms)
- SELECT with ORDER BY and LIMIT scales well
- Knowledge graph queries (1-hop) add minimal overhead

### Long-term Memory (Qdrant)

- Embedding generation is the main latency contributor
- Semantic search is fast once vectors exist (~50-100ms)
- Filtering adds minimal overhead

### Consolidation

- Simple extraction is very fast (<1ms)
- Semantic deduplication adds significant latency (~100-500ms)
- Recommendation: Use hash-based dedup, semantic only for high-importance

## Recommendations

1. **Keep SQLite for short-term**: Performance is excellent
2. **Batch Qdrant operations**: Reduce per-operation overhead
3. **Cache embeddings**: Avoid regenerating for known content
4. **Use hybrid dedup**: Hash first, semantic for borderline cases
5. **Add session memory layer**: Low overhead, high value
