In Azcopy throughput for a single instance will scale at least 20Gbps
Which version of AZCOPY are you using?
You can also perform download/upload speed test: https://www.azurespeed.com/Azure/Download
It also depends on the bandwidth and refer to this article How
Optimize performance in Azcopy
Additional information:
AzCopy will be making three IO Operations for every file: one to get its last modified date, one to read the data, and one to get the last modified date again to check
the file didn't change while we read it. I believe that Azure will count each of those towards the IOPS limit for the disk. So if we take 180 files per second, and multiply that by the 3 operations per file, we get 540 operations per second. That's just above
the 500 operations per second limit of most Standard disks. So that would explain why you can't go any faster.
If you look at disk types and sizes here, you can probably find a large premium disk type with a much higher IPOS limit: https://azure.microsoft.com/en-us/pricing/details/managed-disks/ If
you used a disk like that, it would probably be faster.
