File transfer using fish:// or sftp:// with konqueror is very slow when sending file.

[Moreno Bartalucci]

If I send a file using the konqueror fish:// protocol to another server in the LAN, the transfer speed is about 1Mb/s.
If I do the same operation but *receiving* the same file from the same server, the transfer speed is then about 7Mb/s.

The same result is uploading the same file to the same server using the sftp:// protocol.
Receiving the same file with sftp:// protocol is also very slow (1-1.3Mb/s).

If I upload the same file on the same server using scp from konsole, I have a transfer speed of 6-7Mb/s.

sftp and scp are not the same protocol, but gives the same functionnality. That can explain the difference.
Can you try sftp transfert from the shell of something else and give feedback ?

[Moreno Bartalucci (moreno-bartalucci)]

I focused my attention on the sftp protocol (don't know exactly how to reproduce the behaviour of the fish protocol on the shell).

I tried transferring a file which is 232MB in size (to get significat results).

These are the results using sftp protocol with konqueror:
put -> 0.9MB/s
get -> 1.3 to 1.4MB/s

and with sftp from the shell:
put -> 5.5MB/s
get -> 6.1MB/s

For the shell-based results I'm reporting the average given by the sftp itself. For the konqueror results I noticed that the speed was quite constant over the whole transfer.

Beside the notes I've added as a comment directly in the bug window in
launchpad, I'd like to add something concerning the fish protocol.

I can only test it with konqueror (don't know if it's equivalent to scp or
what else in the shell).

Get -> 6-7MB/s.
Put -> 1MB/s.

P.S. What is the right way to give you feedback? Adding a comment in the bug
window or answering the email?

Thanks.

Marking this as fixed release. My speeds/time it takes to upload and download via fish or sftp are the exact same as they are in using sftp or scp via the command line. Thanks for this report!

I still have the problem on an up-to-date hardy (kde3). Upload to fish url gives about 1MB/s, while it yields 5MB/s with scp.

[Patrick Puddu (patrick-puddu)]

I have the problem still to. Hardy KDE3. Upload with fish 1.2MB/s, with scp over 10MB/s.

Exactly the same problem for me...
I am using Kubuntu Hardy 8.04.1 fully up to date.
