Annotation of embedaddon/rsync/patches/slow-down.diff, revision 1.1

1.1     ! misho       1: This patch adds a --slow-down=USECs option that causes the sender to scan
        !             2: the filelist more slowly, and the generator to scan for deletions more
        !             3: slowly.  It doesn't do anything to make anyone slow down during the normal
        !             4: transfer processing, though.

        !             6: The idea is to lessen rsync's impact on disk I/O.  Unfortunately, there
        !             7: should really be a way to affect more of rsync's processing, perhaps by
        !             8: specifying a maximum disk I/O rate (and have that affect a maximum stat()
        !             9: rate or something like that).
