           Summary: Performance on high BDP networks
           Product: Portable OpenSSH
           Version: 4.6p1
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Build system
        AssignedTo: bitbucket at mindrot.org
        ReportedBy: imorgan at nas.nasa.gov


This bug is intended to raise the priority and formalize the
issues surrounding file transfer performance on high BDP networks.

The performance of file transfers over high BPD networks using OpenSSH
has been know to be an issue for several years now. One patch
that is known to address this issue is the HPN-SSH patch
(http://www.psc.edu/networking/projects/hpn-ssh)

We have been using another patch, proposed by Markus Freidl
(http://marc.theaimsgroup.com/?l=openssh-unix-dev&m=110961193801798&w=2)

It would be greatly appreciated if either a subset of the HPN patch or
Markus Freidl's patch, possibly with some of the scp-specific
improvements from the HPN patch could be incorporated into the
mainstream OpenSSH distribution in the near future.

Thank you
