Description:
It may be a good thing, when memory tables use large pages (should increase performance for big tables and machines with much memory)

How to repeat:
check with cat /proc/meminfo that memory tables don't use hugetlb

How about this feature not for just HEAP tables, but for MYISAM tables? This should give some good benefits when combined with "–myisam_use_mmap=1" no?
