FastOrbs
by CanvasMC
FastOrbs changes how experience orbs merge and get picked up on a Fabric server, with the aim of reducing the work the server does for them.
What it does
The mod replaces the vanilla logic that merges nearby experience orbs with a shorter implementation that checks fewer conditions. Orbs also skip some unnecessary entity checks during merge passes, and the merge check runs every 2 ticks instead of every tick. Newly spawned orbs are combined into existing nearby orbs more efficiently when awarded with a direction.
Pickup is affected too: the 2-tick delay before a player can collect an experience orb is removed, so orbs can be taken immediately. The mod only changes server-side behavior, so players join without installing anything. Files are published for Fabric only, for game versions 26.1 – 26.3, and the code is open source under the GNU General Public License v3.0 only.
Key features
Faster orb merging
Merge logic is rewritten to run with fewer checks than the vanilla routine, so nearby experience orbs combine sooner.
Instant pickup
The short delay before a player can collect an experience orb is removed, so orbs can be taken right away.
Fewer merge checks
Merge passes run every 2 ticks and skip some entity checks that serve no purpose, which lowers the load on the server.
Smarter spawning
New orbs are merged into existing nearby orbs more efficiently when experience is awarded with a direction.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Busy farms and mining
Servers where many experience orbs appear at once, such as mob farms or large mining areas, are where merge and pickup changes are most noticeable.
Vanilla-like play
Because only merging and pickup timing change, the rest of gameplay stays as it is in vanilla.
Who it’s for: Server owners running Fabric who want to change how experience orbs merge and get picked up, without installing anything on players' clients.
