[Xen-users] slow network when interface receiving in xen 3.0.3
Hello all, I''m using Xen 3.0.3 in a production server. I''m not keen on moving to xen 3.1 till soon future. The problem is that network goes slower than it should. Let me explain the symptoms. dom0 --> Network Good! domU --> Network Good! Network --> dom0 Bad! Network --> domU Bad! So when I receive packets it goes 50K/s in a Gigabit connection, but everything goes well when sending. I have being doing some research about this issue in the list and just found problems related to tx checksumming. And I tested it with tcpdump and I don''t have any bad checksumming. Is anyone having network problems like this? is there any bug reported related to this? any clue? Thanks a lot in advanced.
