| <b>Speed</b> & <b>Size</b> | ||
| LZMA-JS 2.0 now minifies to almost half of 1.x and in some cases is 1,000x faster (particularly with high compression). | ||
| It is also more modular. The compression and decompression algorithms can be optionally separated to shrink the file size even more. | ||
