LinearReader replaces Minecraft's region format in order to reduce world size and improve storage efficiency. Chunk data is compressed to the .linear format, instead of vanilla Minecraft's .mca format. The .linear format was created by Xymb-endcrystalme, and can be found on Github.

LinearReader:

  • has an automatic region file backup system
  • uses a region cache to improve performance
  • has a built-in backup system
  • can convert both ways between the .mca and the .linear formats.

For a full description of all of LinearReader's features, see the wiki.

WARNING: LinearReader modifies the way chunk data is saved and makes it more complex. Corruption may occur due to bugs or in unexpected edge cases. Backup your worlds before installing LinearReader.

DISCLAIMER: AI was used to code this mod. I have manually tested and verified that it all works as intended. If you run into any issues please report them on my GitHub and I will try to resolve them as fast as possible.

A note on the graphs:

I performed three tests per platform, using the same seeds for the tests. The data used for the graphs was the combined data of the three tests. All the tests were done with LinearReader version 1.1.0 on my M4 MacBook Air with a render distance of 32 chunks. (Basically, all the tests were performed under identical conditions.)

As mentioned in the wiki, LinearReader initially compresses to a level much lower than 22 (unless otherwise configured). So for LinearReader's disk usage data, I measured both the initial size (which was level 2 compression at the time) of the region files, and then their final size after recompressing them to level 22. Backup files were not included when calculating disk usage.

Total read/write time was calculated as amount of operations x average time for that operation. (For example, Fabric performed roughly triple the amount of read operations that all other platforms did, resulting in Fabric having a much larger total read time value.)

LinearReader can show higher max latency spikes, but those occur primarily during the initial world load. The p95 and p99 values are much closer to what average gameplay is like.
