Without knowing implementation details of the Take function, I know that Arrow uses xsimd and does try to enable the compiler to vectorize code where it can. To clarify, are you asking how to improve the performance you're seeing, or are you asking how to check if the compiled code is using vector instructions? I think a little bit more context about what you know and what you're trying to do could also help others who know more about this function (and vectorization in Arrow in general) to chime in.
