Description

I'm running some microbenchmarks over at https://github.com/andygrove/row-vs-col-rs to compare performance of arrow to just using Vec<> and I'm finding that Arrow is 18x slower in these benchmarks.

I am quite surprised at this performance difference so am creating this issue and will attempt to optimize the code.
