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 to
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.

Looking forward to it. :)
