[SURBL-Announce] Don't use compression on rsync

[Jeff Chan]

Please don't use compression (-z) when rsyncing any zone files,
whether the files are already compressed or not.  Compression
slows down the process since it uses significant CPU on both
sides.  And it certainly would not make sense to try to compress
the already compressed files.  There would be no significant file
size savings, and the CPU usage would be significant.

For rsyncing the uncompressed files, the amount of data
transferred is usually very small since only a few records change
(if any) at any given time, so again compression just adds
unnecessary overhead.

Therefore please don't use the rsync compression option.

Thank you,

Jeff C.
