FTP and SFTP do not support a copy operation. Important. Transfer speed depends on your local connectivity as files are routed through your computer for. When there are many small files this can double or triple transfer speeds because of the parallel execution. Enable Multiple Connections per. › en-us › articles › Cyberduck-How-to-ins.

Cyberduck ftp speed vnc server no displays configured failed

This issue will only be resolved by using parallel requests as OpenSSH does. See d5ae7a7 and aff28eb. ALSO if someone elects SFTP as the transfer protocol it would be nice to have a message stating that there are issues with large transfers and the order of magnitude may be 10x slower as an FYI due to underlying libraries not Cyberduck.

Why the fuck is this thing so slow? Just to say, I've got the same problem with the latest version. Cyberduck is no use to me until this is fixed, so I'd certainly call that a defect rather than an enhancement. Shame, because I like its style. Fugu has a checkbox for this for each connection. Even if it does, the user interface could better clarify this with a "compression" checkbox under "More Options" in the "Open Connection" window.

Of course there are times when this compression is desirable and times when it isn't, so a per-connection setting would be really handy. Cyberduck was always slow and it is still in the 3. Four years and still nothing. This is marked as an enhancement, yet this is quite a major defect.

Enough so to keep me away. I'm sorry? I really like cyberduck for FTP, but marking this major defect as an enhancement makes no sense. SFTP transfers are dog slow, and nearly unusable. Why no love for SFTP? Don't you see all the children crying in the street for reasonable-speed encrypted transfers? So, when replying to this "enhancement", please use the sftp command for comparison, not scp.

Is there a way to solve these speed issues? There's still a lot's of problem in the latest version just downloaded the latest one today 3. If I can be of any help, please let me know. As of Version 3. I added a small patch as a POC for upload limitation. This patch will illustrate that doing parallel request for writing is faster than the current code.

However, due to my little understanding of your code, This POC is a little bit buggy since it will not clear the waiting queue for the last 64 requests And I've got no idea on how to do this with the current framework you're using. So there's still a x2 factor missing somewhere. You could try what impact the cipher has on the transfer speed. We are usually negogiating aesctr wheras OpenSSH prefers aesctr. You could put the weaker cipher on top in BlockCipherFactory.

Thanks for the patch. I have something half-baked here as well and will try to see if I can combine best of both worlds. Ok reading you code, I think that the main problem is that you are waiting for the ACK before continuing to send data, while openSSH just send stuff as fast as it can until he fills the queue, then check for ACK when the sent queue is filled I don't see how the patch attached changes this behaviour.

It will still toggle between writing and reading the status. Let me know the results with the patch attached and how it compares to the previous upload implementation. Yes, but after parallelism requests only. So it doesn't wait for the network latency just after sending the first request and so on Anyway, the main problem of this patch is the lasts 64th requests that aren't checked at the end of the download.

I understand and the patch my own patch attached should fix this issue with the same characteristics of sending out multiple write requests before reading any status. Let me know about the results compared to no parallelism. Thanks again for your help here, much appreciated! Sorry, I don't have the time right now to make the tests, but I will try to look at them this WE.

I go quickly through your patch, and I'm not sure of all the changes you made. I will try to look carefully this WE too. Do you have any other changes in the pipe for SFTP client? So I don't take too much time to change something already changed :. I attached a modified list of the preferred ciphers as a patch. You can experiment with these as well to test if that impacts throughput. I don't have anything else here. The download speed is around the same than previously.

But the window size looks like the same as the one used by cyberduck which looks great :. So the download speed issue is still there. I will try to switch to weaker cipher as suggested in cyberduck, but not sure it's the issue. Yes there's an impact. So I guess that there's still a problem in the download code. I will try to take some time to test it. Hum, still the download speed issue. I tried a higher parallelism factor but that doesn't help. My last guess is that perhaps we are hitting performances issues in the code of the download.

Every file is transfered seperatly, also if I change the maximum number of simultanous connections to 5 or higher. Sorry, something went wrong. I don't understand the issue. The transfer rate is displayed right along the orange coloured status icon while the transfer is in progress. Thats the problem, I dropped a folder with a lot of files and every file is getting processed so fast that I do not see any speed information of any file uploaded within the orange status icon.

Thats what I do see the last 30 minutes, except changing filename, size and percentage. Skip to content. Star 1. New issue. Jump to bottom. Labels enhancement interface User Interface version Milestone 4. Copy link. Attachments Screen shot at Collaborator Author.
