> I optimized BitmapReader in [this
> PR|https://github.com/apache/arrow/pull/6986] and see performance uplift of
> BitmapReader test case. I didn't check other test cases as this change looks
> trivial.
> I reviewed all test cases just now and see big performance drop of 4 cases,
> details at [PR
> link|https://github.com/apache/arrow/pull/6986#issuecomment-616915079].
> I also compared performance of code using BitmapReader, no obvious changes
> found. Looks we should revert that PR.
