Speed

The basics
Every entity in Tibia which is able to move has a certain speed. Monsters have a fixed speed (unless they can use a haste-like spell), and so do NPCs.

However, the speed of players change as they level up. The higher level you have, the faster you are. A level 1 character will have a speed of 220. For each level, you get +2 speed (along with the regular mana and HP gain). A quick calculation will show that a level 111 will move twice as fast as a level 1, and a level 221 will move three times as fast.

Optimizing System Settings
Walking with the arrow keys on the keyboard works a lot better after increasing the repeat rate and reducing the repeat delay of keystrokes. In MS Windows this can be changed in control panel/keyboard.
