Hey Joonsoo,
Any plans to repost these?
I've got some folks with a couple TB of RAM seeing long startup times with $LARGE_DATABASE_PRODUCT. It looks to be contention on hugetlb_instantiation_mutex because everyone is trying to zero hugepages under that lock in parallel. Just removing the lock sped things up quite a bit.
