Describe the Bug

Whenever a train toggles its doors (opening when stopped, closing when moving), I experience major frame drops / lag spikes. I can usually run about 30-60 fps, but when the train doors open/close, I drop to 3-10 fps. This issue is significantly exacerbated when the train has double doors, as I drop to 1 fps for a few seconds.

Reproduction Steps

1. Create a train with train doors.
2. Move the train for a bit.
3. Stop the train, observe lag spike
4. Move the train again, as it starts, observe lag spike.

Expected Result

I expect not to have major frame drops

Additional Context

No response

Facing the same issue (Fabric 1.19.2). As soon as i open train door more than 1-2 times when the train is in assembled form.. FPS Drops to 1 Fps and sometimes client crashes with no crash report or any error in logs. (also happens when u arrive at a station and all doors open at same time... tried disabling that but still happens even if u pass thru 2-3 doors.. open and close them and fps keeps dropping and makes the game unplayable)

Edit: Version- create-fabric-0.5.1-b-build.1089+mc1.19.2.jar
Video for reference- https://www.veed.io/view/bb047299-1337-4514-bfa9-27ee1ad90272?panel=share

Can confirm I'm also seeing this in 0.5.1d on 1.20.1, even on a train with eight doors or so it causes a noticeable lagspike/freeze at the moment all the doors open or close. The more doors, the worse it gets. Testing with 0.5.1b on 1.19.2, the issue is also present but maybe a bit less severe.
I tried disabling some optimization mods like Ferritecore and Lithium and it was still present, so it doesn't seem related to those.

I had the 1.19.2 setup running on a server in the past and can't recall noticing it there, so it could be something that's only happening server-side that would be noticeable in singleplayer.

At first I thought it might be connected to the steam'n'rails addon, but I've got it happening on a bare-minimum setup, so it seems to be purely a Create issue. Interestingly, after pulling a bunch of blocks off of the train, the lag seems to have stopped. after adding a lot on, it gets worse, so it's not just the amount of doors that makes it worse, but also the complexity of the train itself (Though adding more doors will immediately make it a lot worse than more blocks will).

Can you share your modlist (both server and client) with me? even i am facing this issue on my server from months. And i don't think this issue is being worked on so i might aswell trying myself to figure which mod can be the culprit.

Was building an elevator, and it turns out it applies to those too! So I think this can be further marked up as just about any kind of create doors causing lagspikes on assembled contraptions.

Upstream issue, this is less so caused by doors and in reality caused by create joining all the voxel shapes together, which allocates a lot of objects which ends up causing the GC to struggle and in turn cause lag spikes. Doors end up causing triggering this by causing a full recalculation of the voxel shape everytime they open. This will be fixed by upstream eventually once a good enough is solution is found
