What are you virtual machines? Linux, I suppose?

A few aspects of your setup makes the comparison unfair -

1. Since you run untar on the local file system on a physical server, 
the is a possibility to see the effect of write caching.

2. Since glusterfs is working on VMs, the comparison of its performance 
with that on a physical server is not fair.

3. The VMs are hosted on a system with low network bandwidth.

4. The IO throughput inside a VM is limited by the throughput of the 
host file system, in this case - a Windows filesystem (NTFS) ?

What is the amount of RAM on the Windows system hosting the VMs?


PS: Adding gluster-users. The discussion might help others.
