The current OpenBLAS version used in Milvus lacks several key optimizations, particularly in the SGEMM kernel, which plays a critical role in accelerating Faiss’s algorithms. The latest release, OpenBLAS 0.3.29, introduces significant performance improvements, especially for ARM architectures.

To ensure users benefit from the latest BLAS optimizations, could we update the recipe to pin OpenBLAS to version 0.3.29 for non‑x86_64 platforms? Standardizing on this version should provide noticeable speedups and better overall efficiency on ARM-based systems.

Would love to hear thoughts on this!
Thanks for considering this update.

BLAS --> 0.3.9

BLAS --> 0.3.21

Why is this needed?

It seems that we are not using openblas in milvus any more.
