Azure DevOps: Copying files to az fileshare very slow


When I mount an Azure Fileshare from my Azure DevOps pipeline and copy files to the file share via robocopy, this is with 80 Megabytes per minute (12 MBit/s) very slow:

               Total    Copied   Skipped  Mismatch    FAILED    Extras
    Dirs :       456       456       249         0         0         0

I use a StorageV2 account. Azure DevOps and the storage account are in different regions. This is the robocopy command I use:

robocopy ..\my_directory z:\my_directory /E /NS /NC /NP /XD .git /MT:32 /W:5

... and this is how I have mounted the azure fileshare inside the pipeline:

New-PSDrive -Name $(storage.drive) -PSProvider FileSystem -Root "$(storage.unc)" -Persist

Is this normal? How can I make it significantly faster?


Solution

  • It got lightning fast (1 minute, 30 seconds) when I moved the azure fileshare to the same region as the Azure DevOps Pipeline.

    The region of Azure DevOps is displayed in the organizational settings of Azure Devops.
