i did a quick test, how good 'brotli' performs in compression
on binary files versus e.g. xz/lzma...here it is:
bytes:
10.905.600 uncompressed
4.192.280 gzip -9
3.362.626 brotli -11
3.098.216 xz -9 --extreme
3.097.691 lzma -9 --extreme
the uncompressed file is an unsquashfs'ed rootfs from
bin/ar71xx/openwrt-ar71xx-generic-root.squashfs and then
tar'ed.
so nothing to talk about for now, especially the
decompressor is HUGE and this must be taken into account.
bye, bastian
