Project renaming
The project has been renamed from minecraft_world_optimizer to minecraft_world_trimmer as this is a more accurate name.
Features
It is now possible to choose the compression level using a command line argument. The compression level has been reduced to 6 instead of 9 by default.
Bug Fixes
The tool may delete .mcc files from the region folder as it does not supports this file format. It will now only process .mca files.
Performance Improvements
This version improves processing performance and is almost twice as fast than the previous version.
It has been achieved with the following optimizations:
- Stop cloning chunks in memory
- The default compression level is 6 instead of 9
- Do not write the region file if it has not changed
The test world I am using for this benchmark has 29,861 region files for a total of 17,923,667 chunks and 134,079,252 Kilobytes.
| Version 0.1.1 | Version 0.2.0 | Time difference | |
|---|---|---|---|
| Check | 272.12 secs | 269.48 secs | Margin of error |
| Write | 617.65 secs | 310.99 secs | 98% faster |
| Write on already trimmed world | 270.19 secs | 40.73 secs | 663% faster |
| Size on disk after trim | 27,220,256 KB | 27,736,956 KB | 1.8% larger size |
The amount of deleted regions and chunks remains the same.
