VM - CPU load Intel Xeon E5-2683 v4 vs Intel Xeon E5-2683 v3

[antoniogemelli]

Hello guys,

Curiosity, can VM have different performance if host have different CPU?

I have two VMs with same java processes, one use avg 50% of cpu, another 90%

Those VM are in same resource pool, same configuration, same application, the only difference is hardware for cpu in host (who have different cpu).

Thanks
