Raspberry Pi2 or my Synology : rclone too slow



I have a Raspberry Pi 2 and a Synology NAS (ds214+), both are ARM based processor.

I use Rclone to mount my Google Drive account. But the problem is I can’t download at more 8 or 9 MB/s (I have a Fiber 1 Gb).

Is it normal ? Is there a solution ? I have tried 1.36, 1.40 and 1.41 version and have same results.

To mount my google drive, I use this command : “rclone mount secret:/ cloud/”

(On my Windows 10 PC (with a Intel core i5), rclone give me arrount 70 MB/s.)

Here my config file :

type = drive
client_id =
client_secret =
scope = drive
root_folder_id =
service_account_file =
token = {“access_token”:"**",“token_type”:“Bearer”,“refresh_token”:"",“expiry”:“2018-06-13T03:53:06.52663071+02:00”}

type = crypt
remote = Gdrive:/crypt
filename_encryption = standard
directory_name_encryption = false
password = **************
password2 =

Thx for you help :slight_smile:


I think you’ll be running out of CPU on the raspberry PI. Can you check the CPU usage during a transfer and see if you agree?

The crypto stuff (the https transfers in particular) take a lot of CPU on the ARM platform.


Hello, I just check with “htop” and : max CPU ~ 55% (on one Core), average ~ 35%.

And max download was 40 mbit/s (~ 5 MB/s).


And what happens if you download a big file? Try one of these files using wget or curl: https://speed.hetzner.de/

You might want to experiment with --buffer-size make it bigger may help. Also with --drive-chunk-size making that bigger can speed drive transfers.
