Slow Storage access internationally

    Question

  • I work for an Australian based company (but globally accessed.) and we currently have a site hosted in the Australian East regions that I am migrating to a new azure bizspark subscription.  Unfortunately the new bizspark subscription doesn't allow databases created in Australian regions and so i have created the new site in West US 2 region.

    Site consists of Web App, Database and storage account for the storage of photos that can range up to 20mb in size. 

    The images are available on the site through a link to the direct blobUrl and can be downloaded on bulk as a ZIP file that the system builds on the fly. 

    However in the new site I am getting significant delays in accessing the images. I get the following speeds. These are slow speeds cos i have slow internet.  But that is another issue to be resolved. 

    Downloading the blob directly through the Bloburl 20kb to 30kb (150-250 on the Aust East site.)
    Downloading the zip file 50kb-150kb (150-500kb on the Aust East site. )

    Can anyone shed any light on why there is a significant different in the speeds.  Is it just because of the distance? Also, are there tips and tricks for global sites that will minimise download latency internationally.
