Slow upload speed with onedrive

The upload speed is only 1/5 compare with uploading by onedrive website.

Hi~ @20162012 ,

When uploading a large file (more than 4MB) using the OneDrive API, the file must be divided and uploaded.
Because uploads are performed multiple times in small units, Http connection and termination are repeated.
Therefore, uploading takes a lot of time.
It can also be slow depending on the status of the OneDrive API server or the speed between the API server and your computer.

Send us the log file(C:\ProgramData\OpenBoxLab\RaiDrive\log) via e-mail( and we’ll see if there are any other issues.
