40d:Clutter

Workshops will get cluttered when they become full of goods that are not hauled away to stockpiles. A workshop that is cluttered will display (CLT) when viewed via the q or t menus.

Dwarves working in cluttered workshops will work more slowly: even the lowest level of clutter (CLT) doubles the time a workshop task takes. Each successive level of clutter increases the multiplier by one, so tasks performed in a completely cluttered workshop will take ten times as long.

Clutter levels

With larger items (e.g. beds, stones, tables), clutter starts appearing when 15 of those are inside a shop. Every 3 small items counts as one large item, so a craft-making workshop isn't cluttered until there are 45 crafts littering the floors, tables, and possibly walls and ceilings. Siege engine components and ammo are especially large; the siege workshop can get cluttered after producing just 3 ballista arrows.

Levels of Clutter

(CLT)	15 Large Items	: 2x slower
(CLT)	20 Large Items	: 3x slower
(CLT)	25 Large Items	: 4x slower
(CLT)	30 Large Items	: 5x slower
(CLT)	35 Large Items	: 6x slower
(CLT)	40 Large Items	: 7x slower
(CLT)	45 Large Items	: 8x slower
*CLT*	50 Large Items	: 9x slower
☼CLT☼	55 Large Items	: 10x slower

To remedy clutter, be sure to have enough stockpile space of the appropriate kind (using bins will increase stockpile efficiency), and employ enough dwarves with the appropriate hauling jobs (food/furniture/item/refuse/etc.) to get rid of the junk. In many cases it may be faster to build a new workshop, optionally destroying the old one (from the q or t menu).

Certain workshops are more prone to clutter than others. A highly-skilled dwarf with plenty of materials nearby can clutter a workshop rapidly, even if you have many haulers employed. The butcher's workshop can get cluttered even after butchering a single animal: butchering a horse produces 9 meat, 9 chunks, 9 bones, 5 fat, one skull, and one skin.

Similarly, a kitchen producing lavish meals using alcohol, dwarven syrup, or quarry bush leaves can produce a stack of 20 to 100+ prepared meals, which are large items. The kitchen will be cluttered even before the meals are produced: four barrels with 15 units of alcohol each is already 60 large items, causing meal production to take a very long time.

Furnaces and no clutter

As of 0.27.169.33c Furnaces can never get any level of clutter, it is unknown why^[Verify].
