Unfortunately that’s not the case. The patch does nothing to speed up tables.

For some reason or another, you are not getting apples to apples benchmark results.

Could you have different compiler settings when building 5.4 and the array patch? Or maybe official 5.4 distribution and official lua github repo are doing some things differently?

Anyway, to get absolute comparison results with and without  arrays, you can clone ”unmodified” branch from lua-array repository. That’s the state from where I begun working on the patch.
