adding an atime test case; new with optimization to allow avoid [ overhead #PR4488

[DorisAmoakohene]

This regression was reported in #3735. They reported that selecting by row number from a data.table is much slower than from a data.frame.

The pull request that fixed the regression can be found #4488. However, I couldn’t find specific details about the changes made to fix the regression. It’s likely that the changes involved optimizing the way data.table handles row selection to make it more efficient.

something like perf-test-PR4488 would be better

I didnt close it, I renamed the branch and it closed the PR, so the new one can be found here #6290, I am still figuring out how to rename the branch name without having it duplicate the PR
