Hi, with xen paravirt_ops (xen 3.4.0 rc2-pre / 2.6.29-tip) I noticed very bad ethernet throughput. A bit strange - if the traffic goes through an ipsec tunnel all works as expected. What can I do to improve network performance? Greetings jon _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
