For the correct respawn rules have a look here:

5.1 Respawn rules

You will gain many levels when searching for Legendary Items. So sooner or later you need to know the respawn rules to maximize the amount of monsters killed per minute.

1. Every monster on every map will respawn if you rest in a bed.
2. Every monster on a specific map will respawn if you didn't enter that map for 3 minutes.
3. Each 0.5 seconds there is a chance of 1% per respawn area to spawn a monster. This only affects the current map. There are no respawns when the player is in a menu or a fight. If a spawn area has reached its maximum number of monsters, no further monsters respawn in it. So stay on maps with many respawn areas.
4. Monsters could not spawn directly on players, other monsters, obstacles and "event objects". So keep away from small respawn areas.

I recommend going to bed to respawn all monsters.
