Looping over Elements and performing actions gets exponentially slower as the list grows (Java binding web driver 2.45.0)

While the findElementsBy function takes only mere seconds to return a record set, selenium slows down at an exponential rate when performing actions on the record set.

Case in point, I have to loop over 1000 elements and perform a click on each. The findElementsBy function only takes 6 seconds to get all 1000 WebElements, however, looping over each and performing a click takes hours and gets exponentially slower as the iterator processes.

It seems there is a memory leak issue here because even simply grabbing the first element in the list and performing a click on just that element takes 30+ seconds.

When doing a singular findElementBy().click(), the action performs instantly.

I also performed a test by looping over each and simply outputting getText(). You can see as the iterator moves through that each subsequent iteration is twice as slow as the previous.

I also performed another test by getting my 1000 elements. But then I simply called findElement singular again to grab the first element and performed a click. The click still took 30+ seconds. So it seems as though there is definitely a memory issue here.
