[Xen-users] Slow Windows XP 32-bit

[Peter Milesson <miles@xxxxxxxx>]

Hi folks,

Here we go again with the sluggish performance of Windows XP 32-bit 
under Xen 4.3.0. Up till now, I've tested it on AMD hardware, with the 
parameter /PATCHTPR in the boot.ini file of the Windows XP installation. 
It works really great, and Windows XP performance is relly outstanding, 
almost better than on bare metal.
When I use the parameter /PATCHTPR in the boot.ini of a Windows XP 
installation under Intel hardware, it crashes utterly, almost 
immediately during boot. What I could se from the little information 
that's available, the /PATCHTPR parameter only applies to Windows XP 
32-bit, and Windows 2000 running under Xen on AMD hardware.
The Intel Xen installation is almost identical to the one I described in 
my first post a few days ago. It's really annoying and frustrating.
I would be very grateful for some good advice, how to speed up Windows 
XP 32-bit under Xen in Intel hardware.
Best regards,

Peter
