I had to disable both, and PAE. Only APIC=0 would not make any difference. I
will some further testing with Citrix Xenserver 5, using the same virtual
machine and another copy with their vmpd drivers. I bet that there is no
difference in performance. It seems to be a Xen architectural issue. Any
ideas?

Can you have ACPI enabled but APIC disabled, or is that not a valid
configuration?
Or the other way around, can you have ACPI disabled but APIC enabled?
Maybe the APIC emulation is causing a performance loss?
