[CPU usage and memory leak] Deployers lowers the TPS and increasing the frequency of gc.clean() execution

Describe the Bug
When the tree farm moving contraption is activated - the TPS is decreased catastrophically.
I have 24 gigs allocated to server (64 total), Xeon E5 1650 v3 (3.5GHz x 6 cores 12 threads)
The RAM is garbaged catastrophically (+1 gigabyte of garbage every second)
When I activate the simple tree farm from create (with 3 deployers and 3 mechanical saws) - the deployers are lagging the game, and it's lags so much that the server has ~1000 MSPT or 1 TPS.
I use:
- create-fabric 0.5.1.f-build-1333+mc1.18.2
- carpet-fixes-1.18.x-1.7.11 (maybe issue is with that mod?)
- carpet-extra-1.18.2-1.4.72
- fabric-carpet-1.18.2-1.4.69+v22-331
Reproduction Steps
- install create-0.5.1.f
- build a simple contraption with deployers
- watch as your server suffer
Expected Result
no memory and CPU usage leak, better optimization

Other Mods
Suspicious mods:
- carpet-fixes-1.18.x-1.7.11
- carpet-extra-1.18.2-1.4.72
- fabric-carpet-1.18.2-1.4.69+v22-331
- my self-patched factions mod (a mod for chunk claims and towns) - this is probably another mod that causes problem
Additional Context
Also, may you please add a configurable option to deployers that they may not execute very greedy safeOnUse() method?
The Mixin factions$onBlockActivated() is calling factions InteractionManager#onUseBlock which calls InteractionManager#checkPermissions which then calls World#getChunk which is the expensive part here, this isn't related to create at all and is related to whatever factions mod you've got that's mixining into create and running expensive stuff, if this factions mod is your own then you should look into some sort of caching to make calls to checkPermissions much less expensive
