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.
