[Xen-users] GPLPV with my windows 2003 is slow

[Pekka.Panula@xxxxxxxx]

Hi

Installed windows 2003 standard server
(32-bit), Xen 3.2.1 (compiled myself), CentOS 5.2 64-bit as distro.

How come installing GPLPV drivers are
making windows 2003 booting slower and making network slow? 
Boot speed is really good without PV-drivers
and if i am using PV-drivers its starting really slow.

Without GPLPV eg. ping from my remote
locations says: rtt min/avg/max/mdev = 18.219/18.884/19.970/0.588 ms
with GPLPV i am getting: rtt min/avg/max/mdev
= 20.121/75.353/156.815/32.631 ms
If i download from internet some file,
i am getting more consistent network speed without GPLPV drivers and if
using GPLPV i am getting wierd stops when downloading. 

here is my Xen domU config for this
windows if it helps:
---------------------8<------------------------
import os, re
arch = os.uname()[4]
if re.search('64', arch):
    arch_libdir = 'lib64'
else:
    arch_libdir = 'lib'

device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'

name = "w2003"
maxmem = 4095
memory = 2050
vcpus = 1
builder = "hvm"
kernel = "/usr/lib/xen/boot/hvmloader"
boot = "c"
pae = 1
acpi = 1
apic = 1

serial = "pty"
