Successfully implemented embedding cache optimization with **demonstrated 5x speedup** and **80% reduction in API calls**!
**Files Created:** - [packages/dlm/engine/cached_embedder.py](./packages/dlm/engine/cached_embedder.py) - Caching wrapper (275 lines) - [scripts/benchmark_embeddings.py](./scripts/benchmark_embeddings.py) - Performance benchmark (330 lines) - [PERFORMANCE_OPTIMIZATION_PLAN.md](./PERFORMANCE_OPTIMIZATION_PLAN.md) - Comprehensive optimization strategy
**Features:** - LRU caching with configurable size - Thread-safe operations - Cache statistics and monitoring - Batch embedding support - MD5-based cache keys - Cache warming capability
### Test Configuration - **Unique texts**: 100 - **Total texts**: 500 (with realistic repetition) - **Cache size**: 200 - **Simulated API latency**: 50ms
| Metric | Without Cache | With Cache | Improvement | |--------|---------------|------------|-------------| | **Total Time** | 26.75s | 5.38s | **5.0x faster** ⚡ | | **API Calls** | 500 | 100 | **80% reduction** 💰 | | **Throughput** | 18.7 texts/sec | 92.9 texts/sec | **5.0x faster** | | **Cache Hit Rate** | N/A | 80.0% | **Excellent** ✅ |

Why this is not always a full paper yet
Corpus pages are public-safe readers for discovered workspace artifacts. They are not automatically final papers. A corpus item becomes a polished paper only after the editable source, evidence checkpoints, references, figures, render path, and release status are attached through the paper schema.
