Extremely slow download speeds from blob storage

Hi, I'm asking this on behalf of a client that is seeing extremely slow download speeds from blob storage. They are hosting downloads for their website on a blob.core.windows.net subdomain but are experiencing extremely slow download speeds. Unfortunately, I do not have access to their account or additional info about the Azure setup.

Downloads for files can take 30+ minutes with 300mbps connections for users in similar geographic areas, for example.

Any general tips on how to improve the download speed or optimize it, whether the solution is AzureCDN or something else?

An example download link is https://arcos.blob.core.windows.net/arrcus/ArcOS/EFT/v4.1.1.EFT5/VM/ArcOS_4.1.1.EFT5_VM.qcow2?sv=2018-03-28&ss=b&srt=co&sp=rl&se=2020-10-05T16:19:51Z&st=2020-10-05T15:19:51Z&spr=https&sig=4VZNbLUBEquGXD80lSyT8sgbi%2B%2FGaYEMet7E%2FisILwA%3D&rsct=application/octet-stream&rscd=file;%20attachment

    @Mark Yesilevskiy Can you refer to the suggestion mentioned in this Q&A thread and let me know the status

    Performance and scalability checklist for Blob storage

    If you want to specify advanced configuration settings for your CDN endpoint, such as large file download optimization, you can instead use the Azure CDN extension to create a CDN profile and endpoint.use Azure CDN, you may refer to this blog Improve website speed using Azure Storage and Azure CDN

    Sometime issue may be with the webapp environment. Azure published 60 MB/s scalability target for a single blob. If the network and client machine can handle the traffic, then we will send it. For more information see here

    Hope this helps!

    Kindly let us know if the above helps or you need further assistance on this issue.
