First and more pressing issue: Failing to upload files to an SFTP server.
Error: Failed to copy: Update ReadFrom failed: failed to send packet: EOF
Two are in the region of 20GBytes the other 300MBytes.
Another backup to the same server using the same settings (but different source folder/destination folder) seems to work just fine but all the files are < 100MB.
If I upload the un-encrypted directly to the SFTP server it uploads seemingly fine. Updated the SFTP software on the destination to without success.
It also fails via the Rclone Web UI.
Each transfer thread uploads at approx 950KBytes/sec. CPU on the local UnRAID server is a Quad Core E3-1230 V3 (3.3-3.6ghz) and CPU load isn't 100% on any thread.
I can read and write to the local disk at full gigabit so its not a local disk IO issue.
Uploading the files mentioned above one at a time to the SFTP server via Cyberduck gets full line speed (9MBytes/sec) - but obviously unencrypted!
A) Why are these files failing to upload.
B) Why is each transfer thread so slow?
Various, including latest beta: v1.56.0-beta.5356.9e2fbe0f1
