Memanto vs SQLite R_A_G Benchmark Results - Cloud vs Local Memory Systems [P]

I just completed a head-to-head benchmark comparing Memanto's cloud memory system against a custom SQLite RAG implementation for the bounty challenge. The results revealed some interesting architectural insights. Methodology: Dataset: LoCoMo conversational memory benchmark Systems: Memanto (cloud ITS) vs custom SQLite + vector embeddings Evaluation: LLM-as-judge scoring with gemini-3.1-flash-lite Full automation: single CLI command execution Key Results: Memanto : 90% accuracy, 1.878s avg query latency SQLite RAG : 80% accuracy, 2.680s avg query latency Cost : Cloud API fees vs $0 (fully local) Surprising Discovery: The SQLite system's 80% score includes 2 failures that weren't retrieval errors - they were API rate limit hits (HTTP 429). Without those throttling issues, the local system would likely achieve 90-100% accuracy, matching or exceeding Memanto. Architectural Insight: This reveals an interesting resilience pattern: Memanto's cloud architecture naturally buffers against client-side API limits because retrieval and generation are decoupled. Local RAG pipelines sharing API quotas for both embedding and generation are vulnerable to cascading failures under load. Tradeoffs Identified: Memanto : Fast queries, resilient to rate limits, but 14.7s ingestion latency and cloud dependency SQLite RAG : Zero ingestion latency, fully offline, $0 infrastructure, but vulnerable to shared API quotas The complete benchmarking harness and results are available here . Anyone else working on memory system comparisons? Curious about your findings on the cloud vs local tradeoffs. AI #RAG #MemorySystems #Benchmarking submitted by /u/Echo5November [link] [留言]
