Based on the numbers here, I will continue to include some patches or suggestions we got from Haiyang, and send an update later. You should be able to push the update as this seems to be a problem with 3.13 entire tree, then in a separate thread we can identify the missing patches.
These are the numbers that we have when running a simple test with ntttcp. All the below 3 kernels have been installed from the trusty-proposed repo. As a reference, on the same system but with the latest available kernel we have this: Kernel: lts-vivid - 3.19.0.50 (56) Throughput: 12.87Gbps Our historical perf testing includes only kernel 3.16.0-59 for 14.04, for which we got a throughput of 18.02 Gbps. Distribution release: Ubuntu 14.04.3 Kernel: 3.13.0-76-generic (120) Throughput: 1.53Gbps Kernel: 3.13.0-77-generic (121) Throughput: 1.41Gbps Kernel: 3.13.0-78-generic (122) Throughput: 1.50Gbps Going back to try and find a good build, picking up the first 3.13 kernel: Kernel: 3.13.0-24-generic (122) Throughput: 1.50Gbps -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1519897 Title: [Hyper-V] hv: vmbus: Fix a host signaling bug To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1519897/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
