> In ARROW-6478, we switched back to jemallox 4.x to fix a large performance
> regression in micro-benchmarks which appeared when bumping the vendored
> jemalloc version to 5.2.0.
> Since then, the issue was
> [discussed|https://github.com/jemalloc/jemalloc/issues/1621] with the
> jemalloc maintainers and we found out that customizing some options allowed
> regaining all (or most) of the performance on micro-benchmarks with 5.2.x.
