thanks a lot for answers,
in fact here's more informations
ACPI APIC Table: <DELL PE1750 >
FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs
cpu0 (BSP): APIC ID: 0
cpu1 (AP): APIC ID: 1
cpu2 (AP): APIC ID: 6
cpu3 (AP): APIC ID: 7
ioapic0: Changing APIC ID to 8
ioapic1: Changing APIC ID to 9
ioapic2: Changing APIC ID to 10
which mean HTT is enabled in bios... I'll take a look for that. I've to
take out all my vpn connections !
