What the settings do

These values come from our guided editors. Defaults are the editor starting values; they do not show the contents of a customer server.

Save in the background

Off: the server freezes the whole factory on every autosave — on large maps that means seconds of standstill for everyone. On: a child process writes the save while play continues.

Setting
non_blocking_saving
Default
false
Autosave interval

How often Factorio saves on its own. Large factories run more smoothly at 15 to 20 minutes.

Setting
autosave_interval
Default
10
Range / options
1 – 120
Number of autosaves

Factorio keeps this many automatic saves; after that the oldest one is overwritten.

Setting
autosave_slots
Default
5
Range / options
1 – 20
Pause when nobody is playing

The server halts the factory as soon as the last player leaves — nothing keeps running unattended.

Setting
auto_pause
Default
true
Pause while someone joins

Halts the game while a new player downloads the map. Without it, large maps stutter for everyone present.

Setting
auto_pause_when_players_connect
Default
false
Only admins may pause

Stops any guest from halting the running factory.

Setting
only_admins_can_pause_the_game
Default
true
Remove idle players after

0 turns the check off. Otherwise anyone idle for that long leaves the server.

Setting
afk_autokick_interval
Default
0
Range / options
0 – 1440
In-game console commands

Decides who may run commands in chat. Lua commands (/c) mark the save as modified for good.

Setting
allow_commands
Default
admins-only
Range / options
true, false, admins-only
Let regulars in on a full server

Anyone who has played on this server before gets in even when the player limit is reached.

Setting
ignore_player_limit_for_returning_players
Default
false
Upload limit in KB/s

0 means unlimited. A new player downloads the entire map; a limit keeps that download from slowing the running game down.

Setting
max_upload_in_kilobytes_per_second
Default
0
Range / options
0 – 1000000
Simultaneous uploads

This many players may download the map at the same time.

Setting
max_upload_slots
Default
5
Range / options
0 – 64
Minimum latency in ticks

Artificial delay that smooths out brief network jitter. 0 leaves the decision to Factorio.

Setting
minimum_latency_in_ticks
Default
0
Range / options
0 – 60
Save Name

Name of the save file

Setting
SAVE_NAME
Default
saves/default.zip
When it takes effect
Takes effect after saving and restarting the server.
Version

Floating release channel or an explicit version pin. Explicit pins are never advanced automatically.

Setting
FACTORIO_VERSION
Default
stable
When it takes effect
Takes effect after saving and restarting the server.
