           Summary: [manpage] improve documentation of option --block-
           Product: rsync
           Version: 3.0.6
          Platform: Other
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P3
         Component: core
        AssignedTo: wayned at

Cf Debian bug:

Package: rsync
Version: 3.0.6-1
Severity: wishlist

Manual page reads:

       -B, --block-size=BLOCKSIZE

              This forces the block size used in rsync’s
              delta-transfer algorithm to a fixed value.  It is
              normally selected based on the size of each file being
              updated.  See the technical report for details.

However, according to comments in the Net, this can drastically
improve rsync performance on fast networks (1Gb etc). Please include
suggestions and more explanation how would bigger block sizes have
impact on improving the performance of backups.
