I am experiencing very sluggish response with Linux VM's (Debian) running on Hyper-V on a Windows host (Server 2012 R2).



The VM's themselves are not running at 100% CPU and the host itself is reporting very low CPU usage (10%) yet each new VM I create seems to run slower and slower.



I'd understand if the host CPU was running high, or the VM itself, but that is not the case.



It seems with each VM I create, responsiveness gets worse, which I understand points to CPU resource, but I cannot see any indicators as to that being the case.



Responsiveness of the host seems fine, no issues. Memory usage is OK, Disk I/O isn't high... Not sure where to look.



Any pointers would be appreciated, thanks.
