Thread-topic: Performance question on 32-bit HVM DomU vs 64-bit HVM DomU on top of 64-bit Xen Hypervisor

Hello,

 

I’m now doing some network performance testing on running Windows XP on top of a 64-bit Xen Hypervisor, I compared the performance results on a 32-bit Windows XP and a 64-bit Windows XP (both are running as a HVM guest on 64-bit Xen Hypervisor), I found that with a 32-bit windows XP, it performs much slower than 64-bit windows XP, could anyone explain the reason of it?

 

Thanks in advance

Kelven
