Slightly improved GZip compression
Posted: Sat Oct 05, 2019 7:52 am
It is possible to save a bit of space by compressing the gz images in the following way:
1. Create a zip file with any standard tool
2. Recompress it with ECT (https://github.com/fhanau/Efficient-Compression-Tool)
3. Convert it to gz with a tool like kzip2gz (https://encode.su/threads/1630-kzip2gz- ... -converter)
3. Use the tools deflopt (available here: https://github.com/branneman/SpeedyImag ... s/nt/64bit) and defluff (here: https://encode.su/threads/1214-defluff- ... -optimizer) sequentially.
You can save from 0.1% to 5% depending on the original archive.
