Title:
  large rsync runs stall system perfomance (missing --drop-cache)

Status in rsync package in Ubuntu:
  Confirmed

Bug description:
  Please build the package with the --drop-cache patch that is available
  in the tarball, to avoid filling up the io cache with not re-queried
  copied data. The current behavior pushes the data of other process out
  of the cache and thus slows them down.
