Deploying VM using VM template in SCVMM 2012

Hi experts,

I have SCVMM 2012 running on Windows Server 2012 R1.

I have a custom linux VM running on it with two disks.I created a VM template using this VM.

But I have a large disk of size 160GB. So when I deploy a VM using this template, the copy operation is taking a very long time of 3 hours approx. to complete.This is very long, even if I run the SCVMM server in the Same Windows Server.

Any pointers on how to reduce this time?

I even disabled Encryption and used BITS over HTTP. But that does not reduce the time much.

Thanks in advance,

Saleem
