Which is the best way to parameterize check box controls.(Delay in clicking checkboxes )

As seen in the above image, I need to parameterize the check box dynamically from an excel. Currently I am using a combination of both keyword tests(to extract values from the excel) and scripts to dynamically find the element on the page using the previously read value. PFB the code for clicking the check box.

Issue:- It takes atleast 2 mins for this check box to get clicked. the other steps are pretty fast except for this one.

1) Is there any other way to parameterize the check box controls ?

2) Why is the script slowing down at this step?

Thanks in advance.
