Is a similar behavior being observed with Linux guests too?

I also observe that the setup consists of 3.7.8. I would recommend using 
3.7.9 or higher as 3.7.8 had a performance regression problem.

Some windows guests also need tuning to keep CPU consumption under 
control. One such article can be found in the proxmox wiki [1].

HTH,
