azure-rm - download application binaries to the VM takes too much time

[François Déchirot]

Hi,

I am new to Packer. I created some Powershell scripts to download and install specific applications to the image that Packer is building. I have added these scripts to the provisioners section.

I have created a VM in Azure (Standard_NV6 - https://docs.microsoft.com/fr-fr/azure/virtual-machines/windows/sizes-gpu) - identical to the image built by Packer.

If I execute these scripts directly from the VM in Azure, the download time of the applications packages is as follow:

• 1.3GB -> ~3 minutes
• 3GB -> ~5 minutes
• 6.6GB -> 13 minutes

The same scripts executed in the context of Packer:

• 1.3GB -> ~20 minutes
• 3GB -> ~44 minutes
• 6.6GB -> ~100 minutes

How can this be improved? Is it a normal behavior?

Thanks.
