crossing chunkborders near worldspawn and in proximity to worldspawn in its direction cause severe server lag spikes when using caves and cliffs data pack

I can provide video footage if needed or wanted

Duplicate of MC-166005.

Is it really a duplicate tho? I looked at the other issue and i feel like the lag i describe is more specific to the spawn chunks and only happens on the server instance. I havent had this without the data pack either

It seems like a separate bug to me. In my experience MC-166005 seems to get worse the further you are from (0,0).

The symptoms are exactly those described by MC-162253, namely lag spikes when crossing chunk borders in the direction of worldspawn (or chunks loaded by any other means), together with large height differences near those chunks required to trigger the lighting issue. The boundaries where the lag spikes are observed should be render distance away from any chunks in the spawn area (that have sufficient height differences to their neighbors).

You can try increasing the render distance and see if the problematic boundaries move further away from the spawn chunks. In that case this would most certainly be a duplicate of MC-162253.
