Description:

When I map in Dolphin a server over ssh and then do some copying the transfer rate is very low, about 4MB/s. If I map it over FTP it does 25MB/s.
When I copy over scp the speed is good, about 25MB.

I think the problem is in kio slave https://bugs.kde.org/show_bug.cgi?id=218798 and the problem is not resolved for a year and a half still.

On the latest packages in Gentoo I had no problem...

This task depends upon

from what I understand this is an upstream bug of KDE and can be fixed with libssh 0.5 which is supported only in KDE 4.7.

see https://bugs.kde.org/show_bug.cgi?id=254865#c7

That's how I understand it too... But in Gentoo have no problem with it,maybe they patched it somehow in there repo... We'll just have to wait for openssh-0.5.

status with libssh 0.5?

The same:

Over FTP - 70MB/s
Over ssh - 4.2MB/s

Now that's very poor performance...

OK, I have some news from Mr. Andreas Schneider, he says that support in kio_sftp will be released in KDE 4.7

http://quickgit.kde.org/?p=kde-runtime.git&a=commit&h=8eaeb42c787c182b046ce78e5bcdc4069e68c2bb

So, we should wait for kde 4.7 and see :)
