grml-live: ZLIB vs. LZMA
I just made some benchmarks between ZLIB and LZMA compression at squashfs, thanks to grml-live (which provides a commandline option and config option for switching) that’s a trivial task now:
- grml flavour: grml-medium
- using LZMA: 164MB ISO, build time 725 seconds
- using ZLIB: 183MB ISO, build time 254 seconds
So whereas the build time increases the benefit is a smaller ISO, which is quite important for live systems that want to ship as many useful tools as possible. :-)
