How can I raise the speed bridge in XEN 3.2

Good afternoon,
Setting the program Xen 3.2 on Ubuntu 8.04 server (according to this instruction http://howtoforge.com/ubuntu-8.04-server-install-xen-from-ubuntu-repositories) I was faced with the problem I can’t solve. I put DomU in DMZ. In order to do it I made a virtual bridge in Dom0 which connects DomU with Dom0 and LAN. I set routing. While testing I found out that the speed from LAN into DomU is more than 95Mbits/sec, and the speed from DomU into LAN is 100-120Kbits/sec. How can I raise the speed?

Below please find the configuration files:

/etc/xen/xend-config.sxp

Code:

…
(network-script	network-route)
(vif-bridge	xen-br0)
(vif-script	vif-bridge)
…

/etc/xen/domU.cfg

Code:

…
vif = [ ‘bridge=xen-br0’ ]
…

Code:

root@dom0:/etc/xen# brctl show
bridge name     bridge id               STP enabled     interfaces
xen-br0         8000.000000000000       no

Have you tried

Code:

(network-script network-bridge)

instead of

Code:

(network-script	network-route)

in /etc/xen/xend-config.sxp?
