How many chunks are loaded in these servers?

Im playing with only one friend so we are only 2 in the whole server, and I was wondering if there is a way to increase the loaded chunks limit since it seems really low; I can see mobs not burning in daylight until I come really near, and some of my farms dont work even if they are stick to my base.

I basically want to know how many chunks are loaded and if I can change it.
