Benchmarking OpenBLAS vs BLIS

[abitrolly]

Did anybody tried benchmarking BLAS (OpenBLAS) vs BLIS?

I am trying to figure out what is the optimal backend for Homebrew compiled version (https://github.com/Homebrew/homebrew-core/blob/master/Formula/l/llama.cpp.rb).

I guess the right way to test it is to run llama-bench compiled with different options. I am just not sure what the options are, and it takes forever on my 8G sushi laptop.

llama-bench -m ~/.cache/llama.cpp/unsloth_gemma-3-4b-it-GGUF_gemma-3-4b-it-Q4_K_M.gguf
