Hi,

Currently, the 3.4.0 source tar.bz2 is around 240 MiB. Providing an xz
compressed tarball instead would reduce download size for users who
build AOO from source.

Informal comparison between different compressors:
1697468416 aoo-3.4.0-incubating-src.tar
 251417600 aoo-3.4.0-incubating-src.tar.bz2
 207922176 aoo-3.4.0-incubating-src.tar.xz-6e
 199165952 aoo-3.4.0-incubating-src.tar.xz-7e
 190512128 aoo-3.4.0-incubating-src.tar.xz-8e
 187145216 aoo-3.4.0-incubating-src.tar.xz-9e
 168845312 aoo-3.4.0-incubating-src.tar.zpaq-m3-b256
 168816640 aoo-3.4.0-incubating-src.tar.zpaq-m3
 159088640 aoo-3.4.0-incubating-src.tar.zpaq-m4-b256

ZPAQ compresses even better, but compression/decompression is very slow.
It seems that xz -8e would be a good compromise between CPU/memory usage
and compression ratio. It results in a 24% smaller size compared to
bzip2 -9.

Do you agree or have suggestions/concerns?


Best regards,
