Multithread upload speed slowed down to single-thread-speed for Koofr

What is the problem you are having with rclone?

  • roughly a month ago transfer speed for multi-file-transfer ("--transfers 16")¹ slowed down from 32 Mbps² to the speed of a single transfer/thread³ (12 Mbps)
  • happens only when transferring to Koofr⁴, not to pCloud or HiDrive
  • 32 Mbps are still achievable by running multiple separate instances of rclone in parallel⁵
    That's why I think it must be a problem/bug within rclone, not Koofr
    .
    .

¹ same results with --transfers 6, 8 or 12
² max upload of my line
³ command "--transfers 1" or just copying a single file
⁴ Koofr support states not to have changed anything on their side
⁵ that's my actual workaround: I do start 4+ instances using a VB script using one line
objShell.ShellExecute "C:\[snipped]\rclone", "sync D:\src koofr:\dst --include [selection] --transfers 1 ", "", "", 0
per instance.

Run the command 'rclone version' and share the full output of the command.

rclone v1.61.1

  • os/version: Microsoft Windows 10 Pro 21H1 (64 bit)
  • os/kernel: 10.0.19043.1288 (x86_64)
  • os/type: windows
  • os/arch: amd64
  • go/version: go1.19.4
  • go/linking: static
  • go/tags: cmount

Which cloud storage system are you using? (eg Google Drive)

Koofr

The command you were trying to run (eg rclone copy /tmp remote:tmp)

rclone sync D:\src koofr:\dst --transfers 16

The rclone config contents with secrets removed.

[koofr]
type = koofr
provider = koofr
user = [snipped]
password = [snipped]

Hi rcRsc,

Very good tests and post!

I cannot explain nor see how this should suddenly change unless something changed in yours or Koofr's setup a month ago. Sure nothing changed a month ago? (rclone (self)update, network/router update, Windows update,...)

It has sometimes helped to add --disable-http2 in situations like these, did you try that?

indeed, --disable-http2 did the trick.

My sync jobs are automated, I am sure I didn't change anything before the drop (I don't update Windows (I do block all (known) MS-Addresses in the firewall) and usually don't update rclone ("never touch a running system")).
As told, Koofr support said "There were no changes done.", but Hetzner (the host of Koofr servers) might have changed sth?

Anyway, this switch helps, thank you!
