The single instance numbers seem to be within the margin of error, but I would expect multi-instance numbers to show more dramatic changes, due to changes in how workloads converge... Those behave very differently from single instance, especially with the "always set the preferred_nid, even if we moved the task to a node we do NOT prefer" patch... It would be good to understand the behaviour of these patches under more circumstances. -- All rights reversed -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in Please read the FAQ at http://www.tux.org/lkml/
