Server-side TPS lag is not the same as client-side lag. I should check it out one day to see it for myself since my computer is pretty powerful. (Unless it's a lot of entities, then that will induce a strain on both the server and client.) Just checked it out, yeah, it's a lot of item frame entities. My framerate still remains close to 60, but I can see why this is an issue for many. Minecraft is not able to handle that many entities in a small area very well. The sloppy wet noises were quite jarring, only to find out it's a farm with pufferfish...
trust me there are a lot i hae around 150 entetys and i can put like 50 more but i used to have 500 on a crossing
