This is a good news to me. Right. I did some THP migration tests on both x86_64 and IBM ppc64. You can use the code here to test the THP migration, and compare the migration time between 512 base pages and 1 THP. https://github.com/x-y-z/thp-migration-bench NUMA (or fake NUMA) setup and libnuma are needed. Since it simply tries t= o migrate pages from node 0 to node 1. make bench should give you the result like: THP Migration Total time: 676.870346 us Test successful. ------------------- Base Page Migration Total time: 2340.078354 us Test successful. > > And I apology for my slow development over this patchset. > My previous post was about 5 months ago, and I've not done ver.2 due to= > many interruptions.
