CPU Instruction Set Performance

1 post · Nov 2020

What this trail covers

Milvus performance is evaluated across different CPU instruction sets (AVX-512 vs. AVX2) and various vector index types (IVF_FLAT, IVF_SQ8, HNSW). The tests demonstrate that Milvus consistently performs better on AVX-512 due to its 512-bit computation capabilities, although real-world gains are not always double. HNSW index shows superior retrieval speed, while IVF_SQ8 offers a good balance of speed and memory efficiency compared to IVF_FLAT.

  1. Milvus performance on AVX-512 vs. AVX2This post presents a performance comparison of Milvus on systems equipped with AVX-512 versus AVX2 instruction sets. It details the system configuration, Milvus parameters, and the SIFT10M dataset used for testing. Performance results are analyzed for IVF_FLAT, IVF_SQ8, and HNSW index types, showing that AVX-512 generally yields faster retrieval times. The analysis also compares the performance characteristics of the different index types.
