| Instances | 2 | All the Instances present in memory. |
| Signals | 3 | Events, signals, connections, etc. |
| LuaHeap | 4 | All of the data in Luau, including everything happening in core scripts, built-in data types, etc. |
| Script | 5 | All memory being manipulated and referenced by scripts. |
| PhysicsCollision | 6 | Collision detection in the Workspace. |
| BaseParts | 7 | 3D parts used for simulation. |
| GraphicsSolidModels | 8 | Rendering solid models (stuff made with Union, Negate, etc.). |
| GraphicsMeshParts | 10 | Rendering of mesh parts. |
| GraphicsParticles | 11 | Rendering of particles from ParticleEmitters. |
| GraphicsParts | 12 | Rendering of regular parts. |

| GraphicsTerrain | 14 | Rendering of terrain geometry. |
| GraphicsTexture | 15 | Rendering of textures in the game world. |
| GraphicsTextureCharacter | 16 | Rendering of texture composition maps that are generated for Humanoids. |
| Sounds | 17 | Data of sounds in-game. |
| StreamingSounds | 18 | Playback of sounds in-game. |
