Chunk loading now causes severe frametime spikes

This new snapshot severely regressed the frametimes during chunkloading.
The impact seems especially severe in ocean biomes

Reproduction Steps:
- Set your render distance to 32
- Fly around an ocean biome in 25w43a
- Fly around an ocean biome in 25w44a

Observed Results:
- Frametimes are significantly higher and more erratic in 25w44a

Expected Results:
- There wouldn’t be as high of a performance impact
