Originally this got reported via https://github.com/mozilla/geckodriver/issues/729. As it can be seen the time to retrieve elements after reloads of a page increases linear: ** iteration 0 with 1371 elements: 1.21816301346s ** iteration 1 with 1371 elements: 3.68121099472s ** iteration 2 with 1371 elements: 6.05406498909s ** iteration 3 with 1371 elements: 8.95627808571s ** iteration 4 with 1371 elements: 12.4877390862s ** iteration 5 with 1371 elements: 14.9554760456s ** iteration 6 with 1371 elements: 18.0221178532s ** iteration 7 with 1371 elements: 21.0832149982s ** iteration 8 with 1371 elements: 23.2673139572s I wonder if this is causing the slowness of Marionette unit tests especially for debug builds on slow machines like for Android. Maybe we leak memory too. I haven't tested yet how this behaves when working with different web pages.

I wrote a little bit about the performance of Marionette’s known web element store in https://github.com/mozilla/geckodriver/issues/729#issuecomment-303792993.

This problem can no longer be seen since Firefox 84, most likely when enabling our actor implementation by default (bug 1669169), and we actually gained a huge performance boost:
** iteration 0 with 1591 elements: 0.14131402969360352s
** iteration 1 with 1591 elements: 0.10988211631774902s
** iteration 2 with 1591 elements: 0.12004876136779785s
** iteration 3 with 1591 elements: 0.11463093757629395s
** iteration 4 with 1591 elements: 0.11365485191345215s
** iteration 5 with 1591 elements: 0.10502314567565918s
So now it only takes a fraction of the time to retrieve all the requested elements from the page, and that pretty constantly.
