The files used in this test were the files that I distribute with my Stunting Grounds map, same as v0.31 but with minor changes to two of the text files.
Here's what each part of each line stands for in most of the lines: bytes, compression level, compression method, dictionary size, word size, and format. For the last one, solid means that all the files are compressed as a single string, which increases compression slightly but doesn't support modifying the files. The names in the list are, for the most part, the names that I used for the files during testing.
I couldn't go to the max word size for PPMd compression, which is 1536MB (which takes 1567MB to compress), because it said it couldn't allocate enough memory even though I had 2GB free of the 3GB that XP 32bit recognizes.
Here are my results, ordered from least compression to most compression, with the exception of the original size at top.
- 21,798,677 Original size of 10 files and 5 folders
The lines are in the same format as above but with the prefix sf (single file).
- 21,777,641 Original file size
