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?
