Enabling multiple parallel background transfers allows me to more or less triple my speed when uploading multiples files to a remote server via SFTP. The benefit maxes out at ~4 parallel transfers.
This works well when I drag and drop multiple files/folder to the remote directory and let the queue work its magic.
However, when I'm in "keep remote directory up to date" mode and a bunch of new files/directories are detected, the transfer doesn't seem to use parallel transfers and my speed stays at baseline (same as with one file)
Please find attached a log file with the following actions:
1) 5 files are changed in "keep remote directory up to date" mode and transfer speed is baseline. I stopped it after the 1st files transferred to save time.
2) I manually drag and drop the remaining 4 files to the remote directory and multiple parallel transfers happen with speed ~4x baseline.
