Hello all
First of all, thank you for this amazing software. You can’t imagine how many time you saved my life (and my family included 
)
I have decided to write you because i’m facing a quiet strange behavior about slowness on the initial upload on B2.
Before going further, I depict the system here:
System:
Ubuntu 20.04.3 LTS
/dev/nvme0n1p5 234G 108G 114G 49% /
5.11.0-40-generic #44~20.04.2-Ubuntu SMP Tue Oct 26 18:07:44 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
Dupliacti version : Duplicati - 2.0.6.3_beta_2021-06-17
I’m connected via RJ45 to my fiber routing.
I tested my speed via the blackblaze speed test webpage : Test Your Internet Bandwidth Speed
Result:
Download 90.57Mbits
Upload: 11.58 Mbits
Ping: 241ms
Jitter 277,72ms
I have been quite surprised about the ping value so I made a google test:
ping www.google.fr

SO now on my backup side.
I used packet size of 500Mb instead of 50Mb but my upload is around 1.3Mbits or 3Mbits. But nothing more.
I saw some related similar support requests but they are mostly from 2018… so i’m not sure where to start to have a look.
Any advice?
Guillaume.
