-<B>OVERVIEW</B>
-  Particularly when used with the -m (multi-threading) option, gsutil can
-  consume a significant amount of network bandwidth. In some cases this can
-  cause problems, for example if you start a large rsync operation over a
-  network connection used by a number of other important production tasks.
-
-  While gsutil has no built-in support for throttling requests, there are
-  various tools available on Linux and MacOS that can be used to throttle
-  gsutil requests.
-
-  One tool is `trickle<http://monkey.org/~marius/pages/?page=trickle>`_
-  (available via apt-get on Ubuntu systems), which will let you limit how much
-  bandwidth gsutil consumes. For example, the following command would limit
-  upload and download bandwidth consumed by gsutil rsync to 100 KBps:
-
-      trickle -d 100 -u 100 gsutil -m rsync -r ./dir gs://some bucket
-
-  Another tool is
-  `ionice<http://www.tutorialspoint.com/unix_commands/ionice.htm>`_ (built
-  in to many Linux systems), which will let you limit how much I/O capacity
-  gsutil consumes (e.g., to avoid letting it monopolize your local disk). For
-  example, the following command would reduce I/O priority of gsutil so it
-  doesn't monopolize your local disk:
-
-      ionice -c 2 -n 7 gsutil gsutil -m rsync -r ./dir gs://some bucket
