How many cores do your systems usually have ? OpenBLAS's all-or-nothing approach to multithreading is likely to hurt for smallish problems on big machines, though there are some mitigations in place now specifically for ARM servers.

@kroekermartin.bsky.social ~20. But I have the same negative effect when I limit the number of threads, e.g. to 8. That is: much of the time OpenBLAS threading appears to be at best useless, at worst actually negative.
