Good: zlib (as used @rpm5.org) is --rsyncable (and afaik LZMA/XZ is not).

If both the remote/local packages are --rsyncable, then you SHOULD see larger
bandwidth reductions than available with XZ compression and no --rsyncable afaik.

The savings is a difficult measurement however, harder than just comparing file sizes.
