About Inserter Throughput Tooltip
From Factorio Mod PortalHover any inserter (or inserter ghost) to see its maximum throughput in the entity tooltip: items per second with research hand-size bonuses, quality, circuit/manual stack limits, belt stacking and belt speeds taken into account.
Inserter Throughput Tooltip
Hover any inserter, or a ghost you are about to build, and its tooltip tells you how many items per second it can move at most, right where it stands.
What you see
- Max throughput:
80/s (4800/min), chest/machine → belt. The best case for this inserter in its current setup.
Values that involve taking items from a belt are marked with ≈. A note appears when a belt is the bottleneck.
- Upper limit:
120/s (chest → chest, full hand). What the same inserter could do between two chests. - Hand stack size:
16 (5 base + 11 research), belt stacks of 4. Where the hand size comes from. - Cycle:
12 ticks = 0.2 s (swing 2 × 4 + drop 4). Where the time goes. - Measured (optional): items the inserter really moved while you hovered it.
What is taken into account
- Any inserter, including modded ones and custom pickup/drop vectors
- Quality (faster rotation and extension)
- Hand size research and the inserter's built-in stack bonus
- Manual and circuit-set stack size limits
- Item stack size when the moved item is known (in hand or a single whitelist filter)
- Speed of the input and output belt, output lane capacity
- Stack inserter belt stacking, including belt capacity research
- Stacked items on the input belt and pickup lane filters
Accuracy
Every rule was measured in Factorio 2.1.22 by building inserters in a headless server and counting moved items tick by tick, then checked on more than 2,000 random setups:
| Setup | Mean error | |---|---| | chest/machine → chest/machine | 0.2% | | chest/machine → belt | 0.2% | | belt → chest/machine (≈) | ~2% | | belt → belt (≈) | ~2% |
Taking items from a belt is the only approximate part: the hand chases items along the belt, so a small model trained on about 8,000 engine measurements corrects the physics estimate.
Did you know? In 2.1 a fast inserter needs 24 ticks per chest-to-chest cycle, 2.5 items/s per hand item, not 26 ticks and 2.31/s as in older tables.
Assumptions
The value is the best case: a fully compressed input belt, a free output lane, chests and machines that always have items and room. Machine ingredient limits, low power and other inserters taking from the same belt are not included; turn on "Also show measured throughput" to see the real rate.
Settings
- Map: Show hand stack size, cycle time and upper limit (on by default)
- Map: Also show measured throughput (off by default)
- Per player: Also show throughput above the hovered inserter, a text label only you can see (off by default)
Compatibility
- Factorio 2.1.22 or newer. Space Age and Quality are optional.
- Works with modded inserters, ghosts, multiplayer.
- Only inserters that someone is hovering are processed, so there is no cost in big bases.
For modders
local result = remote.call("inserter-throughput", "analyze", entity) -- inserter or inserter ghost
-- result.rate, result.max_rate (items/s), result.cycle (ticks), result.items_per_swing, result.limiter

Пропускная способность манипуляторов
Наведите курсор на манипулятор (или его призрак), и в подсказке появится, сколько предметов в секунду он может переносить максимум в своей текущей установке.
Что показывается: максимальная пропускная способность (с пометкой, если упирается в конвейер), предел для переноса «сундук → сундук», размер пачки с разбивкой (база, исследования, ограничения), цикл в тиках с разбивкой. По желанию: реально измеренная скорость и надпись над манипулятором.
Что учитывается: любые манипуляторы, в том числе модовые; качество; исследования размера пачки; ограничение стопки вручную или по сети; размер стопки предмета; скорость входного и выходного конвейера; укладка стопками у пакетного манипулятора; стопки на входном конвейере; фильтр полос.
Точность: все правила измерены в Factorio 2.1.22 потиково и проверены на 2000+ случайных установках. Сундуки и машины: ошибка 0,2%. Выгрузка на конвейер: 0,2%. Забор с конвейера: около 2%, помечен «≈».
Допущения: показывается лучший случай: входной конвейер полностью сжат, полоса выхода свободна, машины всегда готовы. Реальную скорость покажет опция «Дополнительно показывать измеренную скорость».
Совместимость: Factorio 2.1.22+, Space Age и Quality не обязательны, мультиплеер, призраки, модовые манипуляторы.
