HyperV Server slow to copy files at 5-10mbs

We have a Windows Server 2008R2 SP1 Server with HyperV which has 3 Virtual Servers that run Server 2008R2 SP1 on them.

When we copy from Virtual Server to Virtual Server or from Virtual Server back to itself, the copy speeds are 5-10mbs per second.

How can we make this copying speed faster.

Hello
What is disk system on hyper-v ? is it RAID or standalone sata hdd ?

for hyper-V is recomended RAID 10 level on raid controller with batery and write cache turned on.

see what is VHD file, it is vhd or vhdx ? vhdx - it is newest disk format for VM's

also check performance monitoring to find bottleneck.

see check this guide for optimising Hyper-V performance:
