lag spike when loading world

getting really bad lag spikes when joining a world in single player, game is unplayable for 30 seconds up to a minute before it settles down to normal.

first time i noticed it was in pre4 and it seams like it has become worse in RC1

Here is the world that i made the video in: https://drive.google.com/file/d/1vt_TafzDqCudC6uVvn0M7xW3uqqdDYAG/view?usp=sharing 

however this happens in all worlds after pre4, didn't have this issue in pre3 or earlier.

also if you look in the video how the Memory usage behaves, i think there might be something fishy going on. i've never seen it go past 4gb but for the most part its just running from 0 up to 3999 and then resets and keeps doing that over and over.

Does this issue also happen if you disable all resource packs?

yes, if i remove all resource packs and datapacks it still does this. 

Get a better computer 😃

ok i've done some basic testing and when i removed the 3 armor stands i had in the world(two at spawn and one in my base the loading of the world was much much smoother. so i guess armor stands as an entity is the reason i get massive lag spikes when loading the world. it shouldn't be this bad though with just 3 off them. 

edit: ok so removing the armor stands worked when i had the game running but when i restarted the game the issue returned, the first loading of the world after restart is horrible. 5-15fps for almost a minute before it stabilize and i have the normal 50-70 fps.

Is this still an issue in 1.18.1?

No, I have not experienced this in 1.18 or 1.18.1 it went away during the snapshots, can't remember which version though.
