Uff, my bad, I used an OR here for testing and wrote an AND in the comment. 
Age seems not to matter at all. :)  Regarding the performance, let's compare
your current score with these two cases:

1) adding to the libvirt XML

  <ioapic driver='qemu'/>

right below

  <apic/>

2) loading kvm_amd with avic=0 which will surely disable the AVIC.
