Hello Brett, I would like to share the test we performed.
1. When running the certify-ubuntu-server in the Ubuntu Certification Test Suite (iperf3 stress testing), we noticed that the performance results were below expectations. The speed is only about 70% (expected result: over 80%). (attachment: Ubuntu Certification Test Suite failed result ) 2. Upon further investigation, we found that enabling TSO with the command "ethtool -K <NIC port name> tx on sg on tso on" restored the system’s LOM performance result to the expected level. (attachment: enabling TSO with the command) 3. Based on the results of the second, we would like these NIC features to be enabled by default, ensuring that users do not have to manually set the configuration every time when they execute this test. And we have found a corresponding patch in the upstream kernel. Would it be possible to consider integrating this patch into the Ubuntu 24.04 server version? Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2094764 Title: Enable SG/TSO patch backport request for 24.04 server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2094764/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
