[Bug 989301] Re: large rsync runs stall system perfomance (missing --drop-cache)

[Wayne Davison]

It can easily work on both sides. e.g.:

nocache rsync -aiv --rsync-path='nocache rsync' /src/ host:/dest/

The --rsync-path option tells the remote side it should also use nocache
wrapper.

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.
