zstd at high compression levels (19+) with large dictionaries (32 MB) can match LZMA2 compression level.
- silotis 3y agoAlmost. I tested this a few years ago and IIRC zstd at its highest settings is typically about 5% larger than LZMA. So there is a difference, but probably not enough for most people to care.
- dralley 3y agoI tested recently and (on that selection of data) zstd had better maximum compression at the highest level but took about 3x as long to compress at that level. At most other levels it's faster than xz with slightly worse compression, but not by much.
