⚡ Bolt: optimize synthetic embedding generation#222
Conversation
This commit optimizes the `syntheticVector` generation in `@jeanbot/ai` by: 1. Using the one-shot `crypto.hash` method (Node 22+) instead of `crypto.createHash`. 2. Reducing redundant `normalizeText` calls within the generation loop. Expected Impact: - ~2x speedup in synthetic embedding generation. - Measured improvement from ~7.5ms to ~3.6ms per vector (1536 dimensions). Verification: - Ran `benchmark.ts` to measure execution time and verify determinism. - Ran `pnpm test` to ensure no regressions.

💡 What: The optimization implemented
Optimized the
syntheticVectorgeneration in the@jeanbot/aipackage by leveraging the one-shotcrypto.hashfunction available in Node.js 22 and eliminating redundant string normalization operations.🎯 Why: The performance problem it solves
The previous implementation used
crypto.createHash('sha256').update(...).digest()within a loop of 1536 iterations per vector, and performed redundantnormalizeTextcalls. This created unnecessary object instantiation and CPU overhead for a high-frequency operation.📊 Impact: Expected performance improvement
🔬 Measurement: How to verify the improvement
I created a temporary benchmark script that ran 1000 iterations of
syntheticVectorand compared the total duration before and after the change. Determinism was also verified to ensure the output vectors remained identical.PR created automatically by Jules for task 2725135362605627358 started by @hackerxj2010
