Poor performance to dropbox

[mauricev]

What is the problem you are having with rclone?

Whether I try it from a Mac or Windows (VM), copying fairly large files (tens of GBs) to Dropbox in the cloud never exceeds 18 MB/second. With the Dropbox native client, the performance for the same files borders on 50MB/second.

What is your rclone version (output from rclone version)

v1.53.4

Which OS you are using and how many bits (eg Windows 7, 64 bit)

Mac 10.14.6, Windows 10 2004

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

rclone copy large_file dropbox:

The rclone config contents with secrets removed.

[dropbox]
type = dropbox
token = {"access_token":"redacted","token_type":"bearer","expiry":"0001-01-01T00:00:00Z"}

make sure you have done this

might increase https://rclone.org/dropbox/#dropbox-chunk-size

Have you tried upping --transfers and --checkers?

[mauricev]

I made the first changed and added a chunk size of 149M. That boosted the speed to 29M/second, but that's still way slower than Dropbox's own near 50M/second.

It seems that poor performance with Dropbox is a known issue, and a fix is in progress, https://github.com/rclone/rclone/pull/4656

Yes there are several threads of dropbox performance open at the moment. I hope to have them addressed for 1.55!
