Malloc slack and waste

Hello, I have a question regarding memory slack and waste in UE 5.4. I am trying to reduce memory consumption and using DUMPALLOCS I noticed that we have about 91% malloc efficiency. The slack memory was about 200MB and waste about 150MB. I fiddled with bin sizes and managed to get to efficiency of about 95% but the slack is still pretty high (150MB). Is there any way to reduce it? I tried other allocators but to no major effect.

Do you need it “just for sport”? Or are you really running the project on a machine where 100 megabytes is a large number? :face_with_monocle:

I am trying to run it on Xbox series S and I am looking for all possible memory waste.
