Private server lags more after each restart.

I got "staticobj" and "land" objects spawned in and even after removing them it still lags such as zombies laging behind, doors taking time to open and close and cars bouncing a lot.

I decrased loot in "types.xml", changed weapon
attachments in "spawnabletypes.xml" and as I mentioned addet custom assets and buildings (around 700 objects) but even without them it still lags after restarts.

My internet is good, server provider is close, on PS5.
Only solution for my is reinstaling the server.
