Armor Stands Cause Lag

Armor stands somehow drop my FPS by a concerning amount whenever I look in the direction of where armor stands are present in an area where I have some buildings constructed. Without armor stands there, I get super stable 60 FPS wherever I go around the area while looking at the buildings from 10-30 blocks away. When I place some armor stands in the buildings, for example 9, and go back outside and look at the area while far enough away to have the armor stands fit where I'm facing at on my screen, they cause lag that drops my FPS down to 56. At most, I had 38 armor stands present, and my FPS would be dropped down to around 45, but I'm still shocked that it drops my FPS by 2-4 just with 9 armor stands present. It doesn't lag when I get up close to the armor stands, it only lags when I get a lot of them on my screen (even behind walls) at the same time. The armor stands are equipped with iron armor as well, but I don't think they would normally drop your FPS this much. This report may even be related to the report about the Nether Update bringing unbelievable lag as I'm still experiencing that, so that's just a little heads up.
