Unfortunately even the default Lemmy UI is pretty heavy. A clean load of this page and the comments transferred 1.92MB on the wire (6.61 decompressed). I blame Inferno. Not because Inferno is specifically bad, but because I have been convinced that anything that is React or React-like is bad.
On Diethex it’s 204kB and 217kB respectively, and that’s because the OP’s image is 108kB.
A comparable Reddit page https://www.reddit.com/r/pics/comments/1bja5qu/robert_de_niro_80_and_his_10months_old_daughter/ initially loads about as much as Hexbear, even including all the ad scripts, but transfers megabytes more as you load and scroll comments.
Where they super begin to differ is that one Reddit tab is currently sitting at 400MB+ RAM usage, compared to Hexbear’s 140, compared to Diethex’s 20**.
** I think one thing that is hard to track about page memory usage is the web browser will over-allocate to speed up page navigation and then eventually reclaim when you have mostly settled where you are. So after a few minutes it’s now:
DietHex: 20MB
Hexbear: 60MB
Reddit: 160-260MB
