Did you recently update your #rstats to 4.6? Is your matrix algebra slow? Not #BLAS ting? `sessionInfo()` shows which BLAS library R uses. Switching from reference BLAS to Apple Accelerate is easily a 50x speedup.

Let me know if this worked for you. šŸš€

Partial #performance comparison of #blas / #lapack in #rstats using Xeon E5-2697, i3-12100t, Ultra 7, 265, i7-11000 . The old timer still punches well for its age. Interesting to watch the less than gracious degradation in the AVX512 capable chip (i7)

FlexiBLAS makes this benchmarks a breeze

I wonder if the #lapack that comes with #AOCL is being picked up by flexiblas in #rstats. The things I have to do for the love of electronic health records analytics #bigdata #blas
