Feedback in regards to why bug has been filed: UnixBench parallel test final "System Benchmarks Index Score" run as root, on different size /flavor instances/containers, with different numbers of "copies" of UnixBench. instance cores -> parallel tests c20 c40 x10 2967.7 2844.6 x20 3802.4 3152.3 x40 4304.5 4185.0 x60 4312.2 4321.5
on an otherwise empty node, a c20 and c40 exhibited almost identical performance on a 60-copy UnixBench the c20 must have used more than its allocated resources to match the performance of an instance double its size during a simultaneous identical (x40) test, the node with a c40 had 21-36% higher load average than the node with a c20 this suggests the larger container is using more node resources, as it should (but contradicts the benchmark results) for some reason the larger instance did worse on x10, x20, and x40 tests – this should be verified and investigated -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1639932 Title: cpu constraints not being applied To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nova-lxd/+bug/1639932/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
