commit 236e66481d7d8f61be2f2c1cb81cddb7b9db03d4
Author: Ludovic Courtès <address@hidden>
Date:   Wed Mar 26 15:03:14 2014 +0100

    offload: Allow one transfer in each direction simultaneously.
    
    * guix/scripts/offload.scm (transfer-and-offload): Use 'upload' lock
      instead of 'bandwidth' around 'send-files' calls, and 'download' lock
      around 'retrieve-files' call.

commit 3dfd8af534a7cab94d8bb60c1554944d48911f6c
Author: Ludovic Courtès <address@hidden>
Date:   Wed Mar 26 14:58:00 2014 +0100

    offload: Disable SSH-level compression.
    
    * guix/scripts/offload.scm (remote-pipe): Remove '-z' lsh command line
      argument.  This makes transfers almost an order of magnitude slower.
      OpenSSH's ssh(1) man page notes: "Compression is desirable on modem lines
      and other slow connections, but will only slow down things on fast
      networks."  See also
