Newbie question - upload speed is very low

hello and welcome to the forum,

  • --drive-chunk-size=1024M, that is for gdrive, so can remove that.

  • from the rclone log snippet, rclone is working fine.

  • might increase --transfers and/or --checkers

  • have you tested without mount, without NFS?
    rclone copy /mnt/archives/synology/shadow_full.hbk transfer1: -vv

  • have you tested without rclone?
    on the source machine, create a smb mount and use cp ?

  • 950 Mbps - what kind of test did you run to get that value?
