I am having trouble running gnome-shell smoothly as whenever I try to do any kind of action from moving a window to showing/hiding all applications the gnome-shell process jumps to 100% CPU usage and starts lagging. This is probably due to my unusual hardware setup (I am running a many-core machine with Hyper-Threading disabled).

Here is a system report:

Intel(R) Xeon Phi(TM) CPU 7210 @ 1.30GHz    63  0:71    1500.00 MHz 

Could it be that since a single core is only rated at 1.3 GHz it does not have enough computing power to run gnome-shell?

Is it possible to run gnome-shell on multiple threads/cores?

(Also if it relevant my setup does not support hardware virtualization)

Thanks!
