Manticore’s KNN gets 30% faster with 2‑pass HNSW and AVX‑512
Manticore has rewired its HNSW search loop, moving distance functions from runtime pointers to compile‑time templates and adding a two‑pass neighbor traversal. Combined with batched distance calculations and AVX‑512 SIMD kernels, the changes boost K‑nearest‑neighbor throughput up to 29 % at high k and over 20 % under concurrent load, without API changes or re‑indexing.
