One of the speed-limiting issues with rsync is having to send huge
file lists when mirroring large file systems, even for incremental
updates where only a small part of the file system might have
changed. My proposal is to first send a checksum of the file list
for each directory. If is found to be identical to the same
checksum on the remote side then the list need not be sent for that
directory! That would reduce the size of the file list greatly when
there are directories containing many files which do not change from
on rsync to the next.
How long does it take to calculate the checksum on the remote
directory? Longer than sending the file list? or are you suggesting
the checksums be stored on the source and target somehow?
