           Summary: KIO sftp:/ Slow in KDE 4
           Product: kde
           Version: unspecified
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: senjas at yandex.ru


Version:            (using KDE 4.3.4)
OS:                Linux
Installed from:    openSUSE RPMs

While testing new gigabit-switch, I noticed
that file transfer through KIO sftp:/ is much slower in KDE 4 (.3.4) in my
system compared to KDE 3. I use openSUSE 11.2

What is strange, the problem is seen, when getting files from remote system.
When you put files to remote system through sftp:/, the difference does not
exist (or is much smaller).

For example, when I copy 800 MB file from remote system via sftp:/ in my LAN (1
Gbit Ethernet Switch)...

    * with Konqueror 4 I get 2.3 - 2.7 MB/s
    * with Konqueror 3 I get 10 - 12.4 MB/s

As you see with Konqueror 3 I would get file 4 times faster (1 minute versus 5
minutes).

This affects at least Konqueror 4, Dolphin and Krusader/KDE4 (2.0).
Konqueror 3 and Krusader/KDE3 (1.90) are working fine.
That is why I think that it is KDE 4 KIO sftp:/ problem.

kdebase4-runtime package version is 4.3.4-1.4 (openSUSE package).
