[Bug 1814791] Re: dput's sftp method is very slow

[Roman Shipovskij]

I just installed dput 1.0.3ubuntu1 on Bionic from
https://launchpad.net/ubuntu/+source/dput/1.0.3ubuntu1 and now upload
speed is ~11Mbit/s.

For example, upload speed of Midnight Commander or console sftp is
100Mbit/s which is the physical limit of my network.

Title:
  dput's sftp method is very slow

Status in dput package in Ubuntu:
  Fix Committed

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.
