Blob storage downloading problem

Nikhil Vasdev 0 Reputation points

Hi, I'm getting the issue related to the Azure Blob Storage. When we try to download the video, the speed of downloading is not consistent. Sometimes it takes minutes to download 40-MB video and sometimes it takes 7-8 seconds. How can we resolve that. Please assist me to resolve this issue.

Thank You!

    @Nikhil Vasdev Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

    • How are you downloading the video? Is this specify only for videos or other files?
    • May I know what download speed are getting and How much data are you downloading?
      You can use Azure speed test tool to check the speed:

    Can you try downloading same data using azcopy or Azure Storage explorer tool and check are you getting the same download speed?

    Additional information: There is no throttling on the Azure side below the 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.

    Here's a guide for troubleshooting high E2E latency:

    You can also, refer the below documentation for azure storage performance. If it doesn’t I would recommend you create a technical support ticket to find the root cause of the issue.
