I have an single threaded application who uses 100% cpu on virtual machine under XEN. Adding more VCPU will not help. Is it possible to configure XEN VCPU in order to have better performance with single threaded applications ?

Thanks in advance

You need to get the CPU to give 110%. Talk to Lou Ferrigno. – David Schwartz May 10 '13 at 8:43
If I understand well, I need a faster CPU and you lack an enegger ;-) – hotips May 10 '13 at 9:48
