I was wondering when no using a chunk loader and your on your claims, how many chunks stay loaded while on your claims.
I belive it looks more or less like that- chunk you are in- fully loaded, chunks that are arround you, like 5% speed.
In multiplayer mode, a grid with a default inradius of 10 (for a total of 21x21 or 441) chunks is loaded around each player and sent to the player by default, although this can be configured to be between 3 and 15, usually only lowered with a poor connection home server. Sources- Minecraft wiki
