Configuration

Configuration

Server settings live in config/pipster-server.properties in the server directory. On a singleplayer world, the integrated server uses the game directory's config folder. The file is created with the defaults on the first start. Clients never receive this file.

The defaults are starting values. They are safe for most servers, but they are not performance promises. Measure before and after you change them.

Key	Default	Range	What it does
rebuildVisitsPerTick	4096	16 – 1,048,576	How many pipe nodes a network rebuild may visit per tick. Large networks rebuild over several ticks.
maxNetworkSize	65536	16 – 16,777,216	Networks larger than this stop working and show "Network too large".
syncMergeLimit	4096	0 – 1,048,576	Up to this size, joining two networks is done immediately instead of spread over ticks.
routeCacheEntries	1024	16 – 65,536	Cached routes per network.
routeVisitsPerTick	65536	64 – 16,777,216	Work limit for finding new routes per tick.
endpointAttemptsPerDimension	2048	16 – 1,048,576	How many machine accesses one dimension may make per tick.
slotVisitsPerDimension	32768	64 – 16,777,216	How many inventory slots one dimension may look at per tick.
endpointAttemptsServer	8192	16 – 4,194,304	The same limit for the whole server.
slotVisitsServer	131072	64 – 67,108,864	The same limit for the whole server.
portRefreshesPerTick	256	1 – 65,536	How many ports may re-check their neighbour block per tick after changes.
quarantineTicks	1200	20 – 72,000	How long a misbehaving foreign block is paused (1200 ticks = 1 minute).
acceptForeignPush	true	true/false	Whether Extract/Both ports accept items, fluids and gas that other blocks push in (e.g. machines with auto-output). Energy pushes are always accepted.

When a work limit is reached, ports show "Deferred (server work limit)" and continue the next tick. Nothing is lost.

Datapack options

• Fluid tag #pipster:gaseous: fluids in this tag travel in gas pipes, see Resources and Compatibility.
• All recipes can be replaced with a datapack. Upgrade recipes use the recipe type pipster:empty_contents_shaped, which works like a normal shaped recipe but refuses pipes that still carry content.
