I had the same TPS spike yesterday on 1.21, it too got down to PalettedContainer.serialize(), it's hard to re-produce since it appears to only occur for me after an hour or two (or a lot of chunk loading).

It is worth mentioning that chunk serialization is slow and the time it takes depends on how complex the chunks are. That means, if they have more mobs or block entities, the server will need more time to save them. And the more chunks the server is waiting on to save, the longer the spikes will become as it tries to work through the backlog.

I don't remember getting this before 1.21 though, it's weird. I remember playing 1.20.4 with 20 chunks just like I do now and I wouldn't get this. It still happens with mixin.chunk.serialization=false.
