webdav upload speeds

I am uploading large files using WebDAV and finding that WinSCP is slower than other clients (compared using Cyberduck and davix). As a test, I'm uploading a 100MB file of random text to https://www.webdavserver.com. Are there settings that can be tweaked in WinSCP to improve upload speeds?

The rough speeds I'm getting are:
WinSCP: 700KB/s
Cyberduck: 1.5MB/s
davix: 2.8MB/s

Thank you for your help.

Thanks for your report.
Can you attach corresponding WinSCP and Cyberduck log files?

Re: webdav upload speeds

Thanks, I'm seeing some results I can't explain, but am hoping you could help. I attached 2 log files:

1) main.log: this is the log from my main computer where my upload speed is around 700KB/s. I'm seeing this speed on a couple machines all on my same local network.

2) vm.log: I installed the IE11/Windows 7 VM from https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/ and installed it in VirtualBox on the same machine as above. When I do the transfer there, my upload speed is 2.4MB/s.

Can you see any reason why the VM is faster, or is there more debugging I can do to narrow it down?

Also, if I go in my web browser to https://www.webdavserver.com/ from my main computer, I am able to upload the same 100MB file at 10MB/s. Do you see a reason why uploading in a web browser would be that much faster than WinSCP?

The 100MB test file I'm using is from http://speedtest-sfo1.digitalocean.com.

Thanks for your help.

Re: webdav upload speeds

I have also done some tests. But I cannot reproduce the behaviour you are seeing.

My connection to https://www.webdavserver.com/ has some bottleneck. So both with browser and WinSCP, I get about 600 KB/s.

I've installed a local WebDAV server (IIS). With WinSCP I get about 20 MB/s (2.5 GB file uploads in about 2 minutes). I do not know how to upload a file to a pure WebDAV server with IE. But I've added the server as a "network location" in Windows Explorer. With Windows Explorer, the upload progress bar reaches 100% nearly instantaneously, but then it hangs for the same 2 minutes. So it looks like the speed is again the same as with WinSCP.

Re: webdav upload speeds

Thank you for trying some tests. I can consistently get better speeds uploading to https://www.webdavserver.com with Cyberduck compared to WinSCP. Is there any debugging or extra logging I can do to try to narrow it down more?

What speed to webdavserver do you get with IE?

Please start by attaching a normal session log file both from Cyberduck and WinSCP.
