    The performance among other things would depend on

    • Number of blocks you’re uploading concurrently.
    • Block size.
    • Bandwidth available to you.
    • If or not your worker role and the storage account are not in the same data center/affinity group.

    Take a look at this link: http://msdn.microsoft.com/en-us/library/windowsazure/ee814754.aspx

    What it tells you is that for a “Small” sized VM, you get 100Mbps bandwidth. Ideally if uploading blob in blob storage is the only thing your worker role is doing, I would code the application in such a way that I can make maximum use of this bandwidth available to me.

    Hope this helps.
