I've been exercising the -proposed kernel all day on amd64 using stress- ng memory tests without any observed regressions.
Benchmark comparisons between the current -proposed kernel and the previous xenial kernel show that: 1. stream test: stream test (stress-ng): stress-ng --stream 1 --stream-l3-size 1M -t 60 --metrics-brief -v a 1% to 7% improvement on bogo stream ops per second with stream memory sizes ranging from 1M through to 512M. 2. malloc test: a 13-30% improvement on bogo malloc/free allocations (indirectly using mmap/munmap) for memory sizes ranging from 1M through to 1024M I believe this vindicates the default enabling of THP using enabled=madvise ** Tags removed: verification-needed-xenial ** Tags added: verification-done-xenial -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1703742 Title: Transparent hugepages should default to enabled=madvise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1703742/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
