Cloud Sync between NAS and MS One Drive

[jeyare]

I tried establish new Cloud Sync tasks with new customer, as usual. They use MS One Drive for share with us. Our operation point is Syno Drive 2.0.
My experiences:
- sync from local Syno Drive to Syno Drive server site (NAS) is fast (150Mbps upload)
- sync from Syno Drive (NAS) to MS One Drive is fast (again same upload)
- sync from MS One Drive to Syno Drive (NAS) is horrible (1Gbps download at NAS side)
- sync to local Drive is perfect.

I tried to create a plain file (several attempts) directly at MS One Drive site (abou 20kB, per file). SYnc time was about 1minute!
Then I found tons of info, that One Drive has problem at API level with speed of sync to others cloud systems.
Do you have same experiences?
