[Launchpad Bug Tracker]

This bug was fixed in the package dput - 1.0.3ubuntu1

---------------
dput (1.0.3ubuntu1) eoan; urgency=medium

  [ Julian Andres Klode ]
  * Merge from Debian unstable.  Remaining changes:
    - dput:
      + Recognize 0ubuntu1 as a debian version that requires
        orig.tar.gz to be included in the upload.
      + Correctly handle cases where a non-existant host or no host at all is
        supplied when -o option is passed. (Thanks to David Futcher for
        spotting)
      + Be more careful about setting a variable in a section that does not
        exist in host argument handling.
    - dput.1: Updated to document host argument feature and sftp support.
    - dput.cf:
      + Set 'default_main_host = ubuntu'
      + Set 'progress_indicator = 2'
      + Updated ppa stanza to make use of argument support.
    - dput.cf.5: Updated to note support for sftp transport and host args.
    - dput.cf: Switch ubuntu stanza to upload to "/ubuntu" rather than "/"
      (LP: #1340130).
    - dput.cf: Drop trailing "/ubuntu" from ppa stanza, to support the new
      form of the upload path needed for PPAs based on derived distributions
      (LP: #1340130).
    - Implement a new sftp method that connects via openssh and then
      uses paramiko's sftp support. Some code copied from bzr.
  * sftp: Use bigger chunks when copying files (LP: #1814791)
  * sftp: Handle exceptions during upload, try to remove file

  [ David Lechner ]
  * sftp: fix atomic upload regression for sftp method (LP: #1762572)

dput (1.0.3) unstable; urgency=medium

  * The “سعد راشد محمد الفقيه‎‎ (Sa'ad Rashed Mohammad al-Faqih)”
release.

  [ Ben Finney ]
  * Specify current VCS for this code base.
  * Declare “Standards-Version: 4.3.0”. No additional changes needed.
  * Declare Debhelper compatibility level 12.
  * debian/compat:
    * Remove obsolescent configuration file.
  * Update publication years in copyright notices.

  [ Ondřej Nový ]
  * Remove specification of minimum Python versions.
    The required versions are now in all supported Debian releases.

Title:
  dput's sftp method is very slow

Status in dput package in Ubuntu:
  Fix Released

Bug description:
  Distributor ID:	Ubuntu
  Description:	Ubuntu 18.04.1 LTS
  Release:	18.04
  Codename:	bionic
  dput:           1.0.1ubuntu1

  New dput's sftp method is very slow, ~1.5Mbit/s, after some
  investigation I found that increasing buffer size up to 65536 increase
  upload speed up to ~8Mbit/s, but this is still much slower than old
  method.
