the good news some eviction happens: ```auto evicted_keys:6657536 ``` but yeah, we need to improve on that front. We are working on improving our eviction strategy (cc @realistic-ferret ) ---

hi @resourceful-antelope the PR has been posted. If you build DF by yourself, I would be happy to collaborate with you to do the test. Otherwise, I will let you know when it gets merged and we can use our weekly built docker image. ---
