you are using embed libraries, and because of that you won't get accurate results for a singular addon, basically all the libraries inside aguf are being loaded before any addon, because its the first ace addon in alphabetical order of all your addons.
If you want accurate results you will need to follow the guides to using standalone libraries, then divide the memory usage of those libraries between the addons that use them, it becomes very reasonable :)
I'm seeing this problem as well. After about 30 minutes of playing, the memory attributed to Ace2 increases from 800k to 11M. I'm running disembedded, so memory usage should show up for the library or mod responsible, correct?
